+=head1 SYNOPSIS
+
+    use Carp;
+    croak "We're outta here!";
+
+    use Carp qw(cluck);
+    cluck "This is how we got here!";
+
+    print FH Carp::shortmess("This will have caller's details added");
+    print FH Carp::longmess("This will have stack backtrace added");
+
+=head1 DESCRIPTION
+
+The Carp routines are useful in your own modules because
+they act like die() or warn(), but with a message which is more
+likely to be useful to a user of your module.  In the case of
+cluck, confess, and longmess that context is a summary of every
+call in the call-stack.  For a shorter message you can use carp,
+croak or shortmess which report the error as being from where
+your module was called.  There is no guarantee that that is where
+the error was, but it is a good educated guess.
+
+You can also alter the way the output and logic of C<Carp> works, by
+changing some global variables in the C<Carp> namespace. See the
+section on C<GLOBAL VARIABLES> below.
+
+Here is a more complete description of how shortmess works.  What
+it does is search the call-stack for a function call stack where
+it hasn't been told that there shouldn't be an error.  If every
+call is marked safe, it then gives up and gives a full stack
+backtrace instead.  In other words it presumes that the first likely
+looking potential suspect is guilty.  Its rules for telling whether
+a call shouldn't generate errors work as follows:
+
+=over 4
+
+=item 1.
+
+Any call from a package to itself is safe.
+
+=item 2.
+
+Packages claim that there won't be errors on calls to or from
+packages explicitly marked as safe by inclusion in @CARP_NOT, or
+(if that array is empty) @ISA.  The ability to override what
+@ISA says is new in 5.8.
+
+=item 3.
+
+The trust in item 2 is transitive.  If A trusts B, and B
+trusts C, then A trusts C.  So if you do not override @ISA
+with @CARP_NOT, then this trust relationship is identical to,
+"inherits from".
+
+=item 4.
+
+Any call from an internal Perl module is safe.  (Nothing keeps
+user modules from marking themselves as internal to Perl, but
+this practice is discouraged.)
+
+=item 5.
+
+Any call to Carp is safe.  (This rule is what keeps it from
+reporting the error where you call carp/croak/shortmess.)
+
+=back
+
+=head2 Forcing a Stack Trace
+
+As a debugging aid, you can force Carp to treat a croak as a confess
+and a carp as a cluck across I<all> modules. In other words, force a
+detailed stack trace to be given.  This can be very helpful when trying
+to understand why, or from where, a warning or error is being generated.
+
+This feature is enabled by 'importing' the non-existent symbol
+'verbose'. You would typically enable it by saying
+
+    perl -MCarp=verbose script.pl
+
+or by including the string C<MCarp=verbose> in the PERL5OPT
+environment variable.
+
+Alternately, you can set the global variable C<$Carp::Verbose> to true.
+See the C<GLOBAL VARIABLES> section below.

+
+=head1 GLOBAL VARIABLES
+
+=head2 $Carp::CarpLevel
+
+This variable determines how many call frames are to be skipped when
+reporting where an error occurred on a call to one of C<Carp>'s
+functions. For example:
+
+    $Carp::CarpLevel = 1;
+    sub bar     { .... or _error('Wrong input') }
+    sub _error  { Carp::carp(@_) }
+
+This would make Carp report the error as coming from C<bar>'s caller,
+rather than from C<_error>'s caller, as it normally would.
+
+Defaults to C<0>.
+
+=head2 $Carp::MaxEvalLen
+
+This variable determines how many characters of a string-eval are to
+be shown in the output. Use a value of C<0> to show all text.
+
+Defaults to C<0>.
+
+=head2 $Carp::MaxArgLen
+
+This variable determines how many characters of each argument to a
+function to print. Use a value of C<0> to show the full length of the
+argument.
+
+Defaults to C<64>.
+
+=head2 $Carp::MaxArgNums
+
+This variable determines how many arguments to each function to show.
+Use a value of C<0> to show all arguments to a function call.
+
+Defaults to C<8>.
+
+=head2 $Carp::Verbose
+
+This variable makes C<Carp> use the C<longmess> function at all times.
+This effectively means that all calls to C<carp> become C<cluck> and
+all calls to C<croak> become C<confess>.
+
+Note, this is analogous to using C<use Carp 'verbose'>.
+
+Defaults to C<0>.

+=head1 NAME
+
+Exporter - Implements default import method for modules
+
+=head1 SYNOPSIS
+
+In module YourModule.pm:
+
+  package YourModule;
+  require Exporter;
+  @ISA = qw(Exporter);
+  @EXPORT_OK = qw(munge frobnicate);  # symbols to export on request
+
+or
+
+  package YourModule;
+  use Exporter 'import'; # gives you Exporter's import() method directly
+  @EXPORT_OK = qw(munge frobnicate);  # symbols to export on request
+
+In other files which wish to use YourModule:
+
+  use ModuleName qw(frobnicate);      # import listed symbols
+  frobnicate ($left, $right)          # calls YourModule::frobnicate
+
+=head1 DESCRIPTION
+
+The Exporter module implements an C<import> method which allows a module
+to export functions and variables to its users' namespaces. Many modules
+use Exporter rather than implementing their own C<import> method because
+Exporter provides a highly flexible interface, with an implementation optimised
+for the common case.
+
+Perl automatically calls the C<import> method when processing a
+C<use> statement for a module. Modules and C<use> are documented
+in L<perlfunc> and L<perlmod>. Understanding the concept of
+modules and how the C<use> statement operates is important to
+understanding the Exporter.
+
+=head2 How to Export
+
+The arrays C<@EXPORT> and C<@EXPORT_OK> in a module hold lists of
+symbols that are going to be exported into the users name space by
+default, or which they can request to be exported, respectively.  The
+symbols can represent functions, scalars, arrays, hashes, or typeglobs.
+The symbols must be given by full name with the exception that the
+ampersand in front of a function is optional, e.g.
+
+    @EXPORT    = qw(afunc $scalar @array);   # afunc is a function
+    @EXPORT_OK = qw(&bfunc %hash *typeglob); # explicit prefix on &bfunc
+
+If you are only exporting function names it is recommended to omit the
+ampersand, as the implementation is faster this way.
+
+=head2 Selecting What To Export
+
+Do B<not> export method names!
+
+Do B<not> export anything else by default without a good reason!
+
+Exports pollute the namespace of the module user.  If you must export
+try to use @EXPORT_OK in preference to @EXPORT and avoid short or
+common symbol names to reduce the risk of name clashes.
+
+Generally anything not exported is still accessible from outside the
+module using the ModuleName::item_name (or $blessed_ref-E<gt>method)
+syntax.  By convention you can use a leading underscore on names to
+informally indicate that they are 'internal' and not for public use.
+
+(It is actually possible to get private functions by saying:
+
+  my $subref = sub { ... };
+  $subref->(@args);            # Call it as a function
+  $obj->$subref(@args);        # Use it as a method
+
+However if you use them for methods it is up to you to figure out
+how to make inheritance work.)
+
+As a general rule, if the module is trying to be object oriented
+then export nothing. If it's just a collection of functions then
+@EXPORT_OK anything but use @EXPORT with caution. For function and
+method names use barewords in preference to names prefixed with
+ampersands for the export lists.
+
+Other module design guidelines can be found in L<perlmod>.
+
+=head2 How to Import
+
+In other files which wish to use your module there are three basic ways for
+them to load your module and import its symbols:
+
+=over 4
+
+=item C<use ModuleName;>
+
+This imports all the symbols from ModuleName's @EXPORT into the namespace
+of the C<use> statement.
+
+=item C<use ModuleName ();>
+
+This causes perl to load your module but does not import any symbols.
+
+=item C<use ModuleName qw(...);>
+
+This imports only the symbols listed by the caller into their namespace.
+All listed symbols must be in your @EXPORT or @EXPORT_OK, else an error
+occurs. The advanced export features of Exporter are accessed like this,
+but with list entries that are syntactically distinct from symbol names.
+
+=back
+
+Unless you want to use its advanced features, this is probably all you
+need to know to use Exporter.
+
+=head1 Advanced features
+
+=head2 Specialised Import Lists
+
+If any of the entries in an import list begins with !, : or / then
+the list is treated as a series of specifications which either add to
+or delete from the list of names to import. They are processed left to
+right. Specifications are in the form:
+
+    [!]name         This name only
+    [!]:DEFAULT     All names in @EXPORT
+    [!]:tag         All names in $EXPORT_TAGS{tag} anonymous list
+    [!]/pattern/    All names in @EXPORT and @EXPORT_OK which match
+
+A leading ! indicates that matching names should be deleted from the
+list of names to import.  If the first specification is a deletion it
+is treated as though preceded by :DEFAULT. If you just want to import
+extra names in addition to the default set you will still need to
+include :DEFAULT explicitly.
+
+e.g., Module.pm defines:
+
+    @EXPORT      = qw(A1 A2 A3 A4 A5);
+    @EXPORT_OK   = qw(B1 B2 B3 B4 B5);
+    %EXPORT_TAGS = (T1 => [qw(A1 A2 B1 B2)], T2 => [qw(A1 A2 B3 B4)]);
+
+    Note that you cannot use tags in @EXPORT or @EXPORT_OK.
+    Names in EXPORT_TAGS must also appear in @EXPORT or @EXPORT_OK.
+
+An application using Module can say something like:
+
+    use Module qw(:DEFAULT :T2 !B3 A3);
+
+Other examples include:
+
+    use Socket qw(!/^[AP]F_/ !SOMAXCONN !SOL_SOCKET);
+    use POSIX  qw(:errno_h :termios_h !TCSADRAIN !/^EXIT/);
+
+Remember that most patterns (using //) will need to be anchored
+with a leading ^, e.g., C</^EXIT/> rather than C</EXIT/>.
+
+You can say C<BEGIN { $Exporter::Verbose=1 }> to see how the
+specifications are being processed and what is actually being imported
+into modules.
+
+=head2 Exporting without using Exporter's import method
+
+Exporter has a special method, 'export_to_level' which is used in situations
+where you can't directly call Exporter's import method. The export_to_level
+method looks like:
+
+    MyPackage->export_to_level($where_to_export, $package, @what_to_export);
+
+where $where_to_export is an integer telling how far up the calling stack
+to export your symbols, and @what_to_export is an array telling what
+symbols *to* export (usually this is @_).  The $package argument is
+currently unused.
+
+For example, suppose that you have a module, A, which already has an
+import function:
+
+    package A;
+
+    @ISA = qw(Exporter);
+    @EXPORT_OK = qw ($b);
+
+    sub import
+    {
+	$A::b = 1;     # not a very useful import method
+    }
+
+and you want to Export symbol $A::b back to the module that called 
+package A. Since Exporter relies on the import method to work, via 
+inheritance, as it stands Exporter::import() will never get called. 
+Instead, say the following:
+
+    package A;
+    @ISA = qw(Exporter);
+    @EXPORT_OK = qw ($b);
+
+    sub import
+    {
+	$A::b = 1;
+	A->export_to_level(1, @_);
+    }
+
+This will export the symbols one level 'above' the current package - ie: to 
+the program or module that used package A. 
+
+Note: Be careful not to modify C<@_> at all before you call export_to_level
+- or people using your package will get very unexplained results!
+
+=head2 Exporting without inheriting from Exporter
+
+By including Exporter in your @ISA you inherit an Exporter's import() method
+but you also inherit several other helper methods which you probably don't
+want. To avoid this you can do
+
+  package YourModule;
+  use Exporter qw( import );
+
+which will export Exporter's own import() method into YourModule.
+Everything will work as before but you won't need to include Exporter in
+@YourModule::ISA.
+
+=head2 Module Version Checking
+
+The Exporter module will convert an attempt to import a number from a
+module into a call to $module_name-E<gt>require_version($value). This can
+be used to validate that the version of the module being used is
+greater than or equal to the required version.
+
+The Exporter module supplies a default require_version method which
+checks the value of $VERSION in the exporting module.
+
+Since the default require_version method treats the $VERSION number as
+a simple numeric value it will regard version 1.10 as lower than
+1.9. For this reason it is strongly recommended that you use numbers
+with at least two decimal places, e.g., 1.09.
+
+=head2 Managing Unknown Symbols
+
+In some situations you may want to prevent certain symbols from being
+exported. Typically this applies to extensions which have functions
+or constants that may not exist on some systems.
+
+The names of any symbols that cannot be exported should be listed
+in the C<@EXPORT_FAIL> array.
+
+If a module attempts to import any of these symbols the Exporter
+will give the module an opportunity to handle the situation before
+generating an error. The Exporter will call an export_fail method
+with a list of the failed symbols:
+
+  @failed_symbols = $module_name->export_fail(@failed_symbols);
+
+If the export_fail method returns an empty list then no error is
+recorded and all the requested symbols are exported. If the returned
+list is not empty then an error is generated for each symbol and the
+export fails. The Exporter provides a default export_fail method which
+simply returns the list unchanged.
+
+Uses for the export_fail method include giving better error messages
+for some symbols and performing lazy architectural checks (put more
+symbols into @EXPORT_FAIL by default and then take them out if someone
+actually tries to use them and an expensive check shows that they are
+usable on that platform).
+
+=head2 Tag Handling Utility Functions
+
+Since the symbols listed within %EXPORT_TAGS must also appear in either
+@EXPORT or @EXPORT_OK, two utility functions are provided which allow
+you to easily add tagged sets of symbols to @EXPORT or @EXPORT_OK:
+
+  %EXPORT_TAGS = (foo => [qw(aa bb cc)], bar => [qw(aa cc dd)]);
+
+  Exporter::export_tags('foo');     # add aa, bb and cc to @EXPORT
+  Exporter::export_ok_tags('bar');  # add aa, cc and dd to @EXPORT_OK
+
+Any names which are not tags are added to @EXPORT or @EXPORT_OK
+unchanged but will trigger a warning (with C<-w>) to avoid misspelt tags
+names being silently added to @EXPORT or @EXPORT_OK. Future versions
+may make this a fatal error.
+
+=head2 Generating combined tags
+
+If several symbol categories exist in %EXPORT_TAGS, it's usually
+useful to create the utility ":all" to simplify "use" statements.
+
+The simplest way to do this is:
+
+  %EXPORT_TAGS = (foo => [qw(aa bb cc)], bar => [qw(aa cc dd)]);
+
+  # add all the other ":class" tags to the ":all" class,
+  # deleting duplicates
+  {
+    my %seen;
+
+    push @{$EXPORT_TAGS{all}},
+      grep {!$seen{$_}++} @{$EXPORT_TAGS{$_}} foreach keys %EXPORT_TAGS;
+  }
+
+CGI.pm creates an ":all" tag which contains some (but not really
+all) of its categories.  That could be done with one small
+change:
+
+  # add some of the other ":class" tags to the ":all" class,
+  # deleting duplicates
+  {

+
+=head2 C<AUTOLOAD>ed Constants
+
+Many modules make use of C<AUTOLOAD>ing for constant subroutines to
+avoid having to compile and waste memory on rarely used values (see
+L<perlsub> for details on constant subroutines).  Calls to such
+constant subroutines are not optimized away at compile time because
+they can't be checked at compile time for constancy.
+
+Even if a prototype is available at compile time, the body of the
+subroutine is not (it hasn't been C<AUTOLOAD>ed yet). perl needs to
+examine both the C<()> prototype and the body of a subroutine at
+compile time to detect that it can safely replace calls to that
+subroutine with the constant value.
+
+A workaround for this is to call the constants once in a C<BEGIN> block:
+
+   package My ;
+
+   use Socket ;
+
+   foo( SO_LINGER );     ## SO_LINGER NOT optimized away; called at runtime
+   BEGIN { SO_LINGER }
+   foo( SO_LINGER );     ## SO_LINGER optimized away at compile time.
+
+This forces the C<AUTOLOAD> for C<SO_LINGER> to take place before
+SO_LINGER is encountered later in C<My> package.
+
+If you are writing a package that C<AUTOLOAD>s, consider forcing
+an C<AUTOLOAD> for any constants explicitly imported by other packages
+or which are usually used when your package is C<use>d.

+=head1 NAME
+
+Getopt::Long - Extended processing of command line options
+
+=head1 SYNOPSIS
+
+  use Getopt::Long;
+  my $data   = "file.dat";
+  my $length = 24;
+  my $verbose;
+  $result = GetOptions ("length=i" => \$length,    # numeric
+                        "file=s"   => \$data,      # string
+			"verbose"  => \$verbose);  # flag
+
+=head1 DESCRIPTION
+
+The Getopt::Long module implements an extended getopt function called
+GetOptions(). This function adheres to the POSIX syntax for command
+line options, with GNU extensions. In general, this means that options
+have long names instead of single letters, and are introduced with a
+double dash "--". Support for bundling of command line options, as was
+the case with the more traditional single-letter approach, is provided
+but not enabled by default.
+
+=head1 Command Line Options, an Introduction
+
+Command line operated programs traditionally take their arguments from
+the command line, for example filenames or other information that the
+program needs to know. Besides arguments, these programs often take
+command line I<options> as well. Options are not necessary for the
+program to work, hence the name 'option', but are used to modify its
+default behaviour. For example, a program could do its job quietly,
+but with a suitable option it could provide verbose information about
+what it did.
+
+Command line options come in several flavours. Historically, they are
+preceded by a single dash C<->, and consist of a single letter.
+
+    -l -a -c
+
+Usually, these single-character options can be bundled:
+
+    -lac
+
+Options can have values, the value is placed after the option
+character. Sometimes with whitespace in between, sometimes not:
+
+    -s 24 -s24
+
+Due to the very cryptic nature of these options, another style was
+developed that used long names. So instead of a cryptic C<-l> one
+could use the more descriptive C<--long>. To distinguish between a
+bundle of single-character options and a long one, two dashes are used
+to precede the option name. Early implementations of long options used
+a plus C<+> instead. Also, option values could be specified either
+like
+
+    --size=24
+
+or
+
+    --size 24
+
+The C<+> form is now obsolete and strongly deprecated.
+
+=head1 Getting Started with Getopt::Long
+
+Getopt::Long is the Perl5 successor of C<newgetopt.pl>. This was the
+first Perl module that provided support for handling the new style of
+command line options, hence the name Getopt::Long. This module also
+supports single-character options and bundling. Single character
+options may be any alphabetic character, a question mark, and a dash.
+Long options may consist of a series of letters, digits, and dashes.
+Although this is currently not enforced by Getopt::Long, multiple
+consecutive dashes are not allowed, and the option name must not end
+with a dash.
+
+To use Getopt::Long from a Perl program, you must include the
+following line in your Perl program:
+
+    use Getopt::Long;
+
+This will load the core of the Getopt::Long module and prepare your
+program for using it. Most of the actual Getopt::Long code is not
+loaded until you really call one of its functions.
+
+In the default configuration, options names may be abbreviated to
+uniqueness, case does not matter, and a single dash is sufficient,
+even for long option names. Also, options may be placed between
+non-option arguments. See L<Configuring Getopt::Long> for more
+details on how to configure Getopt::Long.
+
+=head2 Simple options
+
+The most simple options are the ones that take no values. Their mere
+presence on the command line enables the option. Popular examples are:
+
+    --all --verbose --quiet --debug
+
+Handling simple options is straightforward:
+
+    my $verbose = '';	# option variable with default value (false)
+    my $all = '';	# option variable with default value (false)
+    GetOptions ('verbose' => \$verbose, 'all' => \$all);
+
+The call to GetOptions() parses the command line arguments that are
+present in C<@ARGV> and sets the option variable to the value C<1> if
+the option did occur on the command line. Otherwise, the option
+variable is not touched. Setting the option value to true is often
+called I<enabling> the option.
+
+The option name as specified to the GetOptions() function is called
+the option I<specification>. Later we'll see that this specification
+can contain more than just the option name. The reference to the
+variable is called the option I<destination>.
+
+GetOptions() will return a true value if the command line could be
+processed successfully. Otherwise, it will write error messages to
+STDERR, and return a false result.
+
+=head2 A little bit less simple options
+
+Getopt::Long supports two useful variants of simple options:
+I<negatable> options and I<incremental> options.
+
+A negatable option is specified with an exclamation mark C<!> after the
+option name:
+
+    my $verbose = '';	# option variable with default value (false)
+    GetOptions ('verbose!' => \$verbose);
+
+Now, using C<--verbose> on the command line will enable C<$verbose>,
+as expected. But it is also allowed to use C<--noverbose>, which will
+disable C<$verbose> by setting its value to C<0>. Using a suitable
+default value, the program can find out whether C<$verbose> is false
+by default, or disabled by using C<--noverbose>.
+
+An incremental option is specified with a plus C<+> after the
+option name:
+
+    my $verbose = '';	# option variable with default value (false)
+    GetOptions ('verbose+' => \$verbose);
+
+Using C<--verbose> on the command line will increment the value of
+C<$verbose>. This way the program can keep track of how many times the
+option occurred on the command line. For example, each occurrence of
+C<--verbose> could increase the verbosity level of the program.
+
+=head2 Mixing command line option with other arguments
+
+Usually programs take command line options as well as other arguments,
+for example, file names. It is good practice to always specify the
+options first, and the other arguments last. Getopt::Long will,
+however, allow the options and arguments to be mixed and 'filter out'
+all the options before passing the rest of the arguments to the
+program. To stop Getopt::Long from processing further arguments,
+insert a double dash C<--> on the command line:
+
+    --size 24 -- --all
+
+In this example, C<--all> will I<not> be treated as an option, but
+passed to the program unharmed, in C<@ARGV>.
+
+=head2 Options with values
+
+For options that take values it must be specified whether the option
+value is required or not, and what kind of value the option expects.
+
+Three kinds of values are supported: integer numbers, floating point
+numbers, and strings.
+
+If the option value is required, Getopt::Long will take the
+command line argument that follows the option and assign this to the
+option variable. If, however, the option value is specified as
+optional, this will only be done if that value does not look like a
+valid command line option itself.
+
+    my $tag = '';	# option variable with default value
+    GetOptions ('tag=s' => \$tag);
+
+In the option specification, the option name is followed by an equals
+sign C<=> and the letter C<s>. The equals sign indicates that this
+option requires a value. The letter C<s> indicates that this value is
+an arbitrary string. Other possible value types are C<i> for integer
+values, and C<f> for floating point values. Using a colon C<:> instead
+of the equals sign indicates that the option value is optional. In
+this case, if no suitable value is supplied, string valued options get
+an empty string C<''> assigned, while numeric options are set to C<0>.
+
+=head2 Options with multiple values
+
+Options sometimes take several values. For example, a program could
+use multiple directories to search for library files:
+
+    --library lib/stdlib --library lib/extlib
+
+To accomplish this behaviour, simply specify an array reference as the
+destination for the option:
+
+    GetOptions ("library=s" => \@libfiles);
+
+Alternatively, you can specify that the option can have multiple
+values by adding a "@", and pass a scalar reference as the
+destination:
+
+    GetOptions ("library=s@" => \$libfiles);
+
+Used with the example above, C<@libfiles> (or C<@$libfiles>) would
+contain two strings upon completion: C<"lib/srdlib"> and
+C<"lib/extlib">, in that order. It is also possible to specify that
+only integer or floating point numbers are acceptable values.
+
+Often it is useful to allow comma-separated lists of values as well as
+multiple occurrences of the options. This is easy using Perl's split()
+and join() operators:
+
+    GetOptions ("library=s" => \@libfiles);
+    @libfiles = split(/,/,join(',',@libfiles));
+
+Of course, it is important to choose the right separator string for
+each purpose.
+
+Warning: What follows is an experimental feature.
+
+Options can take multiple values at once, for example
+
+    --coordinates 52.2 16.4 --rgbcolor 255 255 149
+
+This can be accomplished by adding a repeat specifier to the option
+specification. Repeat specifiers are very similar to the C<{...}>
+repeat specifiers that can be used with regular expression patterns.
+For example, the above command line would be handled as follows:
+
+    GetOptions('coordinates=f{2}' => \@coor, 'rgbcolor=i{3}' => \@color);
+
+The destination for the option must be an array or array reference.
+
+It is also possible to specify the minimal and maximal number of
+arguments an option takes. C<foo=s{2,4}> indicates an option that
+takes at least two and at most 4 arguments. C<foo=s{,}> indicates one
+or more values; C<foo:s{,}> indicates zero or more option values.
+
+=head2 Options with hash values
+
+If the option destination is a reference to a hash, the option will
+take, as value, strings of the form I<key>C<=>I<value>. The value will
+be stored with the specified key in the hash.
+
+    GetOptions ("define=s" => \%defines);
+
+Alternatively you can use:
+
+    GetOptions ("define=s%" => \$defines);
+
+When used with command line options:
+
+    --define os=linux --define vendor=redhat
+
+the hash C<%defines> (or C<%$defines>) will contain two keys, C<"os">
+with value C<"linux> and C<"vendor"> with value C<"redhat">. It is
+also possible to specify that only integer or floating point numbers
+are acceptable values. The keys are always taken to be strings.
+
+=head2 User-defined subroutines to handle options
+
+Ultimate control over what should be done when (actually: each time)
+an option is encountered on the command line can be achieved by
+designating a reference to a subroutine (or an anonymous subroutine)
+as the option destination. When GetOptions() encounters the option, it
+will call the subroutine with two or three arguments. The first
+argument is the name of the option. For a scalar or array destination,
+the second argument is the value to be stored. For a hash destination,
+the second arguments is the key to the hash, and the third argument
+the value to be stored. It is up to the subroutine to store the value,
+or do whatever it thinks is appropriate.
+
+A trivial application of this mechanism is to implement options that
+are related to each other. For example:
+
+    my $verbose = '';	# option variable with default value (false)
+    GetOptions ('verbose' => \$verbose,
+	        'quiet'   => sub { $verbose = 0 });
+
+Here C<--verbose> and C<--quiet> control the same variable
+C<$verbose>, but with opposite values.
+
+If the subroutine needs to signal an error, it should call die() with
+the desired error message as its argument. GetOptions() will catch the
+die(), issue the error message, and record that an error result must
+be returned upon completion.
+
+If the text of the error message starts with an exclamation mark C<!>
+it is interpreted specially by GetOptions(). There is currently one
+special command implemented: C<die("!FINISH")> will cause GetOptions()
+to stop processing options, as if it encountered a double dash C<-->.
+
+=head2 Options with multiple names
+
+Often it is user friendly to supply alternate mnemonic names for
+options. For example C<--height> could be an alternate name for
+C<--length>. Alternate names can be included in the option
+specification, separated by vertical bar C<|> characters. To implement
+the above example:
+
+    GetOptions ('length|height=f' => \$length);
+
+The first name is called the I<primary> name, the other names are
+called I<aliases>. When using a hash to store options, the key will
+always be the primary name.
+
+Multiple alternate names are possible.
+
+=head2 Case and abbreviations
+
+Without additional configuration, GetOptions() will ignore the case of
+option names, and allow the options to be abbreviated to uniqueness.
+
+    GetOptions ('length|height=f' => \$length, "head" => \$head);
+
+This call will allow C<--l> and C<--L> for the length option, but
+requires a least C<--hea> and C<--hei> for the head and height options.
+
+=head2 Summary of Option Specifications
+
+Each option specifier consists of two parts: the name specification
+and the argument specification.
+
+The name specification contains the name of the option, optionally
+followed by a list of alternative names separated by vertical bar
+characters.
+
+    length	      option name is "length"
+    length|size|l     name is "length", aliases are "size" and "l"
+
+The argument specification is optional. If omitted, the option is
+considered boolean, a value of 1 will be assigned when the option is
+used on the command line.
+
+The argument specification can be
+
+=over 4
+
+=item !
+
+The option does not take an argument and may be negated by prefixing
+it with "no" or "no-". E.g. C<"foo!"> will allow C<--foo> (a value of
+1 will be assigned) as well as C<--nofoo> and C<--no-foo> (a value of
+0 will be assigned). If the option has aliases, this applies to the
+aliases as well.
+
+Using negation on a single letter option when bundling is in effect is
+pointless and will result in a warning.
+
+=item +
+
+The option does not take an argument and will be incremented by 1
+every time it appears on the command line. E.g. C<"more+">, when used
+with C<--more --more --more>, will increment the value three times,
+resulting in a value of 3 (provided it was 0 or undefined at first).
+
+The C<+> specifier is ignored if the option destination is not a scalar.
+
+=item = I<type> [ I<desttype> ] [ I<repeat> ]
+
+The option requires an argument of the given type. Supported types
+are:
+
+=over 4
+
+=item s
+
+String. An arbitrary sequence of characters. It is valid for the
+argument to start with C<-> or C<-->.
+
+=item i
+
+Integer. An optional leading plus or minus sign, followed by a
+sequence of digits.
+
+=item o
+
+Extended integer, Perl style. This can be either an optional leading
+plus or minus sign, followed by a sequence of digits, or an octal
+string (a zero, optionally followed by '0', '1', .. '7'), or a
+hexadecimal string (C<0x> followed by '0' .. '9', 'a' .. 'f', case
+insensitive), or a binary string (C<0b> followed by a series of '0'
+and '1').
+
+=item f
+
+Real number. For example C<3.14>, C<-6.23E24> and so on.
+
+=back
+
+The I<desttype> can be C<@> or C<%> to specify that the option is
+list or a hash valued. This is only needed when the destination for
+the option value is not otherwise specified. It should be omitted when
+not needed.
+
+The I<repeat> specifies the number of values this option takes per
+occurrence on the command line. It has the format C<{> [ I<min> ] [ C<,> [ I<max> ] ] C<}>.
+
+I<min> denotes the minimal number of arguments. It defaults to 1 for
+options with C<=> and to 0 for options with C<:>, see below. Note that
+I<min> overrules the C<=> / C<:> semantics.
+
+I<max> denotes the maximum number of arguments. It must be at least
+I<min>. If I<max> is omitted, I<but the comma is not>, there is no
+upper bound to the number of argument values taken.
+
+=item : I<type> [ I<desttype> ]
+
+Like C<=>, but designates the argument as optional.
+If omitted, an empty string will be assigned to string values options,
+and the value zero to numeric options.
+
+Note that if a string argument starts with C<-> or C<-->, it will be
+considered an option on itself.
+
+=item : I<number> [ I<desttype> ]
+
+Like C<:i>, but if the value is omitted, the I<number> will be assigned.
+
+=item : + [ I<desttype> ]
+
+Like C<:i>, but if the value is omitted, the current value for the
+option will be incremented.
+
+=back
+
+=head1 Advanced Possibilities
+
+=head2 Object oriented interface
+
+Getopt::Long can be used in an object oriented way as well:
+
+    use Getopt::Long;
+    $p = new Getopt::Long::Parser;
+    $p->configure(...configuration options...);
+    if ($p->getoptions(...options descriptions...)) ...
+
+Configuration options can be passed to the constructor:
+
+    $p = new Getopt::Long::Parser
+             config => [...configuration options...];
+
+=head2 Thread Safety
+
+Getopt::Long is thread safe when using ithreads as of Perl 5.8.  It is
+I<not> thread safe when using the older (experimental and now
+obsolete) threads implementation that was added to Perl 5.005.
+
+=head2 Documentation and help texts
+
+Getopt::Long encourages the use of Pod::Usage to produce help
+messages. For example:
+
+    use Getopt::Long;
+    use Pod::Usage;
+
+    my $man = 0;
+    my $help = 0;
+
+    GetOptions('help|?' => \$help, man => \$man) or pod2usage(2);
+    pod2usage(1) if $help;
+    pod2usage(-exitstatus => 0, -verbose => 2) if $man;

+
+=head2 Storing option values in a hash
+
+Sometimes, for example when there are a lot of options, having a
+separate variable for each of them can be cumbersome. GetOptions()
+supports, as an alternative mechanism, storing options in a hash.
+
+To obtain this, a reference to a hash must be passed I<as the first
+argument> to GetOptions(). For each option that is specified on the
+command line, the option value will be stored in the hash with the
+option name as key. Options that are not actually used on the command
+line will not be put in the hash, on other words,
+C<exists($h{option})> (or defined()) can be used to test if an option
+was used. The drawback is that warnings will be issued if the program
+runs under C<use strict> and uses C<$h{option}> without testing with
+exists() or defined() first.
+
+    my %h = ();
+    GetOptions (\%h, 'length=i');	# will store in $h{length}
+
+For options that take list or hash values, it is necessary to indicate
+this by appending an C<@> or C<%> sign after the type:
+
+    GetOptions (\%h, 'colours=s@');	# will push to @{$h{colours}}
+
+To make things more complicated, the hash may contain references to
+the actual destinations, for example:
+
+    my $len = 0;
+    my %h = ('length' => \$len);
+    GetOptions (\%h, 'length=i');	# will store in $len
+
+This example is fully equivalent with:
+
+    my $len = 0;
+    GetOptions ('length=i' => \$len);	# will store in $len
+
+Any mixture is possible. For example, the most frequently used options
+could be stored in variables while all other options get stored in the
+hash:
+
+    my $verbose = 0;			# frequently referred
+    my $debug = 0;			# frequently referred
+    my %h = ('verbose' => \$verbose, 'debug' => \$debug);
+    GetOptions (\%h, 'verbose', 'debug', 'filter', 'size=i');
+    if ( $verbose ) { ... }
+    if ( exists $h{filter} ) { ... option 'filter' was specified ... }
+
+=head2 Bundling
+
+With bundling it is possible to set several single-character options
+at once. For example if C<a>, C<v> and C<x> are all valid options,
+
+    -vax
+
+would set all three.
+
+Getopt::Long supports two levels of bundling. To enable bundling, a
+call to Getopt::Long::Configure is required.
+
+The first level of bundling can be enabled with:
+
+    Getopt::Long::Configure ("bundling");
+
+Configured this way, single-character options can be bundled but long
+options B<must> always start with a double dash C<--> to avoid
+ambiguity. For example, when C<vax>, C<a>, C<v> and C<x> are all valid
+options,
+
+    -vax
+
+would set C<a>, C<v> and C<x>, but
+
+    --vax
+
+would set C<vax>.
+
+The second level of bundling lifts this restriction. It can be enabled
+with:
+
+    Getopt::Long::Configure ("bundling_override");
+
+Now, C<-vax> would set the option C<vax>.
+
+When any level of bundling is enabled, option values may be inserted
+in the bundle. For example:
+
+    -h24w80
+
+is equivalent to
+
+    -h 24 -w 80
+
+When configured for bundling, single-character options are matched
+case sensitive while long options are matched case insensitive. To
+have the single-character options matched case insensitive as well,
+use:
+
+    Getopt::Long::Configure ("bundling", "ignorecase_always");
+
+It goes without saying that bundling can be quite confusing.
+
+=head2 The lonesome dash
+
+Normally, a lone dash C<-> on the command line will not be considered
+an option. Option processing will terminate (unless "permute" is
+configured) and the dash will be left in C<@ARGV>.
+
+It is possible to get special treatment for a lone dash. This can be
+achieved by adding an option specification with an empty name, for
+example:
+
+    GetOptions ('' => \$stdio);
+
+A lone dash on the command line will now be a legal option, and using
+it will set variable C<$stdio>.
+
+=head2 Argument callback
+
+A special option 'name' C<< <> >> can be used to designate a subroutine
+to handle non-option arguments. When GetOptions() encounters an
+argument that does not look like an option, it will immediately call this
+subroutine and passes it one parameter: the argument name.
+
+For example:
+
+    my $width = 80;
+    sub process { ... }
+    GetOptions ('width=i' => \$width, '<>' => \&process);
+
+When applied to the following command line:
+
+    arg1 --width=72 arg2 --width=60 arg3
+
+This will call
+C<process("arg1")> while C<$width> is C<80>,
+C<process("arg2")> while C<$width> is C<72>, and
+C<process("arg3")> while C<$width> is C<60>.
+
+This feature requires configuration option B<permute>, see section
+L<Configuring Getopt::Long>.
+
+=head1 Configuring Getopt::Long
+
+Getopt::Long can be configured by calling subroutine
+Getopt::Long::Configure(). This subroutine takes a list of quoted
+strings, each specifying a configuration option to be enabled, e.g.
+C<ignore_case>, or disabled, e.g. C<no_ignore_case>. Case does not
+matter. Multiple calls to Configure() are possible.
+
+Alternatively, as of version 2.24, the configuration options may be
+passed together with the C<use> statement:
+
+    use Getopt::Long qw(:config no_ignore_case bundling);
+
+The following options are available:
+
+=over 12
+
+=item default
+
+This option causes all configuration options to be reset to their
+default values.
+
+=item posix_default
+
+This option causes all configuration options to be reset to their
+default values as if the environment variable POSIXLY_CORRECT had
+been set.
+
+=item auto_abbrev
+
+Allow option names to be abbreviated to uniqueness.
+Default is enabled unless environment variable
+POSIXLY_CORRECT has been set, in which case C<auto_abbrev> is disabled.
+
+=item getopt_compat
+
+Allow C<+> to start options.
+Default is enabled unless environment variable
+POSIXLY_CORRECT has been set, in which case C<getopt_compat> is disabled.
+
+=item gnu_compat
+
+C<gnu_compat> controls whether C<--opt=> is allowed, and what it should
+do. Without C<gnu_compat>, C<--opt=> gives an error. With C<gnu_compat>,
+C<--opt=> will give option C<opt> and empty value.
+This is the way GNU getopt_long() does it.
+
+=item gnu_getopt
+
+This is a short way of setting C<gnu_compat> C<bundling> C<permute>
+C<no_getopt_compat>. With C<gnu_getopt>, command line handling should be
+fully compatible with GNU getopt_long().
+
+=item require_order
+
+Whether command line arguments are allowed to be mixed with options.
+Default is disabled unless environment variable
+POSIXLY_CORRECT has been set, in which case C<require_order> is enabled.
+
+See also C<permute>, which is the opposite of C<require_order>.
+
+=item permute
+
+Whether command line arguments are allowed to be mixed with options.
+Default is enabled unless environment variable
+POSIXLY_CORRECT has been set, in which case C<permute> is disabled.
+Note that C<permute> is the opposite of C<require_order>.
+
+If C<permute> is enabled, this means that
+
+    --foo arg1 --bar arg2 arg3
+
+is equivalent to
+
+    --foo --bar arg1 arg2 arg3
+
+If an argument callback routine is specified, C<@ARGV> will always be
+empty upon successful return of GetOptions() since all options have been
+processed. The only exception is when C<--> is used:
+
+    --foo arg1 --bar arg2 -- arg3
+
+This will call the callback routine for arg1 and arg2, and then
+terminate GetOptions() leaving C<"arg2"> in C<@ARGV>.
+
+If C<require_order> is enabled, options processing
+terminates when the first non-option is encountered.
+
+    --foo arg1 --bar arg2 arg3
+
+is equivalent to
+
+    --foo -- arg1 --bar arg2 arg3
+
+If C<pass_through> is also enabled, options processing will terminate
+at the first unrecognized option, or non-option, whichever comes
+first.
+
+=item bundling (default: disabled)
+
+Enabling this option will allow single-character options to be
+bundled. To distinguish bundles from long option names, long options
+I<must> be introduced with C<--> and bundles with C<->.
+
+Note that, if you have options C<a>, C<l> and C<all>, and
+auto_abbrev enabled, possible arguments and option settings are:
+
+    using argument               sets option(s)
+    ------------------------------------------
+    -a, --a                      a
+    -l, --l                      l
+    -al, -la, -ala, -all,...     a, l
+    --al, --all                  all
+
+The surprising part is that C<--a> sets option C<a> (due to auto
+completion), not C<all>.
+
+Note: disabling C<bundling> also disables C<bundling_override>.
+
+=item bundling_override (default: disabled)
+
+If C<bundling_override> is enabled, bundling is enabled as with
+C<bundling> but now long option names override option bundles.
+
+Note: disabling C<bundling_override> also disables C<bundling>.
+
+B<Note:> Using option bundling can easily lead to unexpected results,
+especially when mixing long options and bundles. Caveat emptor.
+
+=item ignore_case  (default: enabled)
+
+If enabled, case is ignored when matching long option names. If,
+however, bundling is enabled as well, single character options will be
+treated case-sensitive.
+
+With C<ignore_case>, option specifications for options that only
+differ in case, e.g., C<"foo"> and C<"Foo">, will be flagged as
+duplicates.
+
+Note: disabling C<ignore_case> also disables C<ignore_case_always>.
+
+=item ignore_case_always (default: disabled)
+
+When bundling is in effect, case is ignored on single-character
+options also.
+
+Note: disabling C<ignore_case_always> also disables C<ignore_case>.
+
+=item auto_version (default:disabled)
+
+Automatically provide support for the B<--version> option if
+the application did not specify a handler for this option itself.
+
+Getopt::Long will provide a standard version message that includes the
+program name, its version (if $main::VERSION is defined), and the
+versions of Getopt::Long and Perl. The message will be written to
+standard output and processing will terminate.
+
+C<auto_version> will be enabled if the calling program explicitly
+specified a version number higher than 2.32 in the C<use> or
+C<require> statement.
+
+=item auto_help (default:disabled)
+
+Automatically provide support for the B<--help> and B<-?> options if
+the application did not specify a handler for this option itself.
+
+Getopt::Long will provide a help message using module L<Pod::Usage>. The
+message, derived from the SYNOPSIS POD section, will be written to
+standard output and processing will terminate.
+
+C<auto_help> will be enabled if the calling program explicitly
+specified a version number higher than 2.32 in the C<use> or
+C<require> statement.
+
+=item pass_through (default: disabled)
+
+Options that are unknown, ambiguous or supplied with an invalid option
+value are passed through in C<@ARGV> instead of being flagged as
+errors. This makes it possible to write wrapper scripts that process
+only part of the user supplied command line arguments, and pass the
+remaining options to some other program.
+
+If C<require_order> is enabled, options processing will terminate at
+the first unrecognized option, or non-option, whichever comes first.
+However, if C<permute> is enabled instead, results can become confusing.
+
+Note that the options terminator (default C<-->), if present, will
+also be passed through in C<@ARGV>.
+
+=item prefix
+
+The string that starts options. If a constant string is not
+sufficient, see C<prefix_pattern>.
+
+=item prefix_pattern
+
+A Perl pattern that identifies the strings that introduce options.
+Default is C<--|-|\+> unless environment variable
+POSIXLY_CORRECT has been set, in which case it is C<--|->.
+
+=item long_prefix_pattern
+
+A Perl pattern that allows the disambiguation of long and short
+prefixes. Default is C<-->.
+
+Typically you only need to set this if you are using nonstandard
+prefixes and want some or all of them to have the same semantics as
+'--' does under normal circumstances.
+
+For example, setting prefix_pattern to C<--|-|\+|\/> and
+long_prefix_pattern to C<--|\/> would add Win32 style argument
+handling.

+=item debug (default: disabled)
+
+Enable debugging output.

+the standard message.
+
+=item *
+
+A numeric value corresponding to the desired exit status.
+
+=item *
+
+A reference to a hash.
+
+=back
+
+If more than one argument is given then the entire argument list is
+assumed to be a hash.  If a hash is supplied (either as a reference or
+as a list) it should contain one or more elements with the following
+keys:
+
+=over 4
+
+=item C<-message>
+
+=item C<-msg>
+
+The text of a message to print immediately prior to printing the
+program's usage message.
+
+=item C<-exitval>
+
+The desired exit status to pass to the B<exit()> function.
+This should be an integer, or else the string "NOEXIT" to
+indicate that control should simply be returned without
+terminating the invoking process.
+
+=item C<-output>
+
+A reference to a filehandle, or the pathname of a file to which the
+usage message should be written. The default is C<\*STDERR> unless the
+exit value is less than 2 (in which case the default is C<\*STDOUT>).
+
+=back
+
+You cannot tie this routine directly to an option, e.g.:
+
+    GetOptions("version" => \&VersionMessage);
+
+Use this instead:
+
+    GetOptions("version" => sub { VersionMessage() });
+
+=item HelpMessage
+
+This subroutine produces a standard help message, derived from the
+program's POD section SYNOPSIS using L<Pod::Usage>. It takes the same
+arguments as VersionMessage(). In particular, you cannot tie it
+directly to an option, e.g.:
+
+    GetOptions("help" => \&HelpMessage);
+
+Use this instead:
+
+    GetOptions("help" => sub { HelpMessage() });
+
+=back
+
+=head1 Return values and Errors
+
+Configuration errors and errors in the option definitions are
+signalled using die() and will terminate the calling program unless
+the call to Getopt::Long::GetOptions() was embedded in C<eval { ...
+}>, or die() was trapped using C<$SIG{__DIE__}>.
+
+GetOptions returns true to indicate success.
+It returns false when the function detected one or more errors during
+option parsing. These errors are signalled using warn() and can be
+trapped with C<$SIG{__WARN__}>.
+
+=head1 Legacy
+
+The earliest development of C<newgetopt.pl> started in 1990, with Perl
+version 4. As a result, its development, and the development of
+Getopt::Long, has gone through several stages. Since backward
+compatibility has always been extremely important, the current version
+of Getopt::Long still supports a lot of constructs that nowadays are
+no longer necessary or otherwise unwanted. This section describes
+briefly some of these 'features'.
+
+=head2 Default destinations
+
+When no destination is specified for an option, GetOptions will store
+the resultant value in a global variable named C<opt_>I<XXX>, where
+I<XXX> is the primary name of this option. When a progam executes
+under C<use strict> (recommended), these variables must be
+pre-declared with our() or C<use vars>.
+
+    our $opt_length = 0;
+    GetOptions ('length=i');	# will store in $opt_length
+
+To yield a usable Perl variable, characters that are not part of the
+syntax for variables are translated to underscores. For example,
+C<--fpp-struct-return> will set the variable
+C<$opt_fpp_struct_return>. Note that this variable resides in the
+namespace of the calling program, not necessarily C<main>. For
+example:
+
+    GetOptions ("size=i", "sizes=i@");
+
+with command line "-size 10 -sizes 24 -sizes 48" will perform the
+equivalent of the assignments
+
+    $opt_size = 10;
+    @opt_sizes = (24, 48);
+
+=head2 Alternative option starters
+
+A string of alternative option starter characters may be passed as the
+first argument (or the first argument after a leading hash reference
+argument).
+
+    my $len = 0;
+    GetOptions ('/', 'length=i' => $len);
+
+Now the command line may look like:
+
+    /length 24 -- arg
+
+Note that to terminate options processing still requires a double dash
+C<-->.
+
+GetOptions() will not interpret a leading C<< "<>" >> as option starters
+if the next argument is a reference. To force C<< "<" >> and C<< ">" >> as
+option starters, use C<< "><" >>. Confusing? Well, B<using a starter
+argument is strongly deprecated> anyway.
+
+=head2 Configuration variables
+
+Previous versions of Getopt::Long used variables for the purpose of
+configuring. Although manipulating these variables still work, it is
+strongly encouraged to use the C<Configure> routine that was introduced
+in version 2.17. Besides, it is much easier.
+
+=head1 Trouble Shooting
+
+=head2 GetOptions does not return a false result when an option is not supplied
+
+That's why they're called 'options'.
+
+=head2 GetOptions does not split the command line correctly
+
+The command line is not split by GetOptions, but by the command line
+interpreter (CLI). On Unix, this is the shell. On Windows, it is
+COMMAND.COM or CMD.EXE. Other operating systems have other CLIs.
+
+It is important to know that these CLIs may behave different when the
+command line contains special characters, in particular quotes or
+backslashes. For example, with Unix shells you can use single quotes
+(C<'>) and double quotes (C<">) to group words together. The following
+alternatives are equivalent on Unix:
+
+    "two words"
+    'two words'
+    two\ words
+
+In case of doubt, insert the following statement in front of your Perl
+program:
+
+    print STDERR (join("|",@ARGV),"\n");
+
+to verify how your CLI passes the arguments to the program.
+
+=head2 Undefined subroutine &main::GetOptions called
+
+Are you running Windows, and did you write
+
+    use GetOpt::Long;
+
+(note the capital 'O')?
+
+=head2 How do I put a "-?" option into a Getopt::Long?
+
+You can only obtain this using an alias, and Getopt::Long of at least
+version 2.13.
+
+    use Getopt::Long;
+    GetOptions ("help|?");    # -help and -? will both set $opt_help

+=head1 NAME
+
+constant - Perl pragma to declare constants
+
+=head1 SYNOPSIS
+
+    use constant PI    => 4 * atan2(1, 1);
+    use constant DEBUG => 0;
+
+    print "Pi equals ", PI, "...\n" if DEBUG;
+
+    use constant {
+        SEC   => 0,
+        MIN   => 1,
+        HOUR  => 2,
+        MDAY  => 3,
+        MON   => 4,
+        YEAR  => 5,
+        WDAY  => 6,
+        YDAY  => 7,
+        ISDST => 8,
+    };
+
+    use constant WEEKDAYS => qw(
+        Sunday Monday Tuesday Wednesday Thursday Friday Saturday
+    );
+
+    print "Today is ", (WEEKDAYS)[ (localtime)[WDAY] ], ".\n";
+
+=head1 DESCRIPTION
+
+This will declare a symbol to be a constant with the given value.
+
+When you declare a constant such as C<PI> using the method shown
+above, each machine your script runs upon can have as many digits
+of accuracy as it can use. Also, your program will be easier to
+read, more likely to be maintained (and maintained correctly), and
+far less likely to send a space probe to the wrong planet because
+nobody noticed the one equation in which you wrote C<3.14195>.
+
+When a constant is used in an expression, perl replaces it with its
+value at compile time, and may then optimize the expression further.
+In particular, any code in an C<if (CONSTANT)> block will be optimized
+away if the constant is false.
+
+=head1 NOTES
+
+As with all C<use> directives, defining a constant happens at
+compile time. Thus, it's probably not correct to put a constant
+declaration inside of a conditional statement (like C<if ($foo)
+{ use constant ... }>).
+
+Constants defined using this module cannot be interpolated into
+strings like variables.  However, concatenation works just fine:
+
+    print "Pi equals PI...\n";        # WRONG: does not expand "PI"
+    print "Pi equals ".PI."...\n";    # right
+
+Even though a reference may be declared as a constant, the reference may
+point to data which may be changed, as this code shows.
+
+    use constant ARRAY => [ 1,2,3,4 ];
+    print ARRAY->[1];
+    ARRAY->[1] = " be changed";
+    print ARRAY->[1];
+
+Dereferencing constant references incorrectly (such as using an array
+subscript on a constant hash reference, or vice versa) will be trapped at
+compile time.
+
+Constants belong to the package they are defined in.  To refer to a
+constant defined in another package, specify the full package name, as
+in C<Some::Package::CONSTANT>.  Constants may be exported by modules,
+and may also be called as either class or instance methods, that is,
+as C<< Some::Package->CONSTANT >> or as C<< $obj->CONSTANT >> where
+C<$obj> is an instance of C<Some::Package>.  Subclasses may define
+their own constants to override those in their base class.
+
+The use of all caps for constant names is merely a convention,
+although it is recommended in order to make constants stand out
+and to help avoid collisions with other barewords, keywords, and
+subroutine names. Constant names must begin with a letter or
+underscore. Names beginning with a double underscore are reserved. Some
+poor choices for names will generate warnings, if warnings are enabled at
+compile time.
+
+=head2 List constants
+
+Constants may be lists of more (or less) than one value.  A constant
+with no values evaluates to C<undef> in scalar context.  Note that
+constants with more than one value do I<not> return their last value in
+scalar context as one might expect.  They currently return the number
+of values, but B<this may change in the future>.  Do not use constants
+with multiple values in scalar context.
+
+B<NOTE:> This implies that the expression defining the value of a
+constant is evaluated in list context.  This may produce surprises:
+
+    use constant TIMESTAMP => localtime;                # WRONG!
+    use constant TIMESTAMP => scalar localtime;         # right
+
+The first line above defines C<TIMESTAMP> as a 9-element list, as
+returned by localtime() in list context.  To set it to the string
+returned by localtime() in scalar context, an explicit C<scalar>
+keyword is required.
+
+List constants are lists, not arrays.  To index or slice them, they
+must be placed in parentheses.
+
+    my @workdays = WEEKDAYS[1 .. 5];            # WRONG!
+    my @workdays = (WEEKDAYS)[1 .. 5];          # right
+
+=head2 Defining multiple constants at once
+
+Instead of writing multiple C<use constant> statements, you may define
+multiple constants in a single statement by giving, instead of the
+constant name, a reference to a hash where the keys are the names of
+the constants to be defined.  Obviously, all constants defined using
+this method must have a single value.
+
+    use constant {
+        FOO => "A single value",
+        BAR => "This", "won't", "work!",        # Error!
+    };
+
+This is a fundamental limitation of the way hashes are constructed in
+Perl.  The error messages produced when this happens will often be
+quite cryptic -- in the worst case there may be none at all, and
+you'll only later find that something is broken.
+
+When defining multiple constants, you cannot use the values of other
+constants defined in the same declaration.  This is because the
+calling package doesn't know about any constant within that group
+until I<after> the C<use> statement is finished.
+
+    use constant {
+        BITMASK => 0xAFBAEBA8,
+        NEGMASK => ~BITMASK,                    # Error!
+    };
+
+=head2 Magic constants
+
+Magical values and references can be made into constants at compile
+time, allowing for way cool stuff like this.  (These error numbers
+aren't totally portable, alas.)
+
+    use constant E2BIG => ($! = 7);
+    print   E2BIG, "\n";        # something like "Arg list too long"
+    print 0+E2BIG, "\n";        # "7"
+
+You can't produce a tied constant by giving a tied scalar as the
+value.  References to tied variables, however, can be used as
+constants without any problems.
+
+=head1 TECHNICAL NOTES
+
+In the current implementation, scalar constants are actually
+inlinable subroutines. As of version 5.004 of Perl, the appropriate
+scalar constant is inserted directly in place of some subroutine
+calls, thereby saving the overhead of a subroutine call. See
+L<perlsub/"Constant Functions"> for details about how and when this
+happens.
+
+In the rare case in which you need to discover at run time whether a
+particular constant has been declared via this module, you may use
+this function to examine the hash C<%constant::declared>. If the given
+constant name does not include a package name, the current package is
+used.
+
+    sub declared ($) {
+        use constant 1.01;              # don't omit this!
+        my $name = shift;
+        $name =~ s/^::/main::/;
+        my $pkg = caller;
+        my $full_name = $name =~ /::/ ? $name : "${pkg}::$name";
+        $constant::declared{$full_name};
+    }
+
+=head1 BUGS
+
+In the current version of Perl, list constants are not inlined
+and some symbols may be redefined without generating a warning.
+
+It is not possible to have a subroutine or a keyword with the same
+name as a constant in the same package. This is probably a Good Thing.
+
+A constant with a name in the list C<STDIN STDOUT STDERR ARGV ARGVOUT
+ENV INC SIG> is not allowed anywhere but in package C<main::>, for
+technical reasons. 
+
+Unlike constants in some languages, these cannot be overridden
+on the command line or via environment variables.
+
+You can get into trouble if you use constants in a context which
+automatically quotes barewords (as is true for any subroutine call).
+For example, you can't say C<$hash{CONSTANT}> because C<CONSTANT> will
+be interpreted as a string.  Use C<$hash{CONSTANT()}> or
+C<$hash{+CONSTANT}> to prevent the bareword quoting mechanism from
+kicking in.  Similarly, since the C<< => >> operator quotes a bareword
+immediately to its left, you have to say C<< CONSTANT() => 'value' >>
+(or simply use a comma in place of the big arrow) instead of
+C<< CONSTANT => 'value' >>.

+=head1 NAME
+
+strict - Perl pragma to restrict unsafe constructs
+
+=head1 SYNOPSIS
+
+    use strict;
+
+    use strict "vars";
+    use strict "refs";
+    use strict "subs";
+
+    use strict;
+    no strict "vars";
+
+=head1 DESCRIPTION
+
+If no import list is supplied, all possible restrictions are assumed.
+(This is the safest mode to operate in, but is sometimes too strict for
+casual programming.)  Currently, there are three possible things to be
+strict about:  "subs", "vars", and "refs".
+
+=over 6
+
+=item C<strict refs>
+
+This generates a runtime error if you 
+use symbolic references (see L<perlref>).
+
+    use strict 'refs';
+    $ref = \$foo;
+    print $$ref;	# ok
+    $ref = "foo";
+    print $$ref;	# runtime error; normally ok
+    $file = "STDOUT";
+    print $file "Hi!";	# error; note: no comma after $file
+
+There is one exception to this rule:
+
+    $bar = \&{'foo'};
+    &$bar;
+
+is allowed so that C<goto &$AUTOLOAD> would not break under stricture.
+
+
+=item C<strict vars>
+
+This generates a compile-time error if you access a variable that wasn't
+declared via C<our> or C<use vars>,
+localized via C<my()>, or wasn't fully qualified.  Because this is to avoid
+variable suicide problems and subtle dynamic scoping issues, a merely
+local() variable isn't good enough.  See L<perlfunc/my> and
+L<perlfunc/local>.
+
+    use strict 'vars';
+    $X::foo = 1;	 # ok, fully qualified
+    my $foo = 10;	 # ok, my() var
+    local $foo = 9;	 # blows up
+
+    package Cinna;
+    our $bar;			# Declares $bar in current package
+    $bar = 'HgS';		# ok, global declared via pragma
+
+The local() generated a compile-time error because you just touched a global
+name without fully qualifying it.
+
+Because of their special use by sort(), the variables $a and $b are
+exempted from this check.
+
+=item C<strict subs>
+
+This disables the poetry optimization, generating a compile-time error if
+you try to use a bareword identifier that's not a subroutine, unless it
+is a simple identifier (no colons) and that it appears in curly braces or
+on the left hand side of the C<< => >> symbol.
+
+    use strict 'subs';
+    $SIG{PIPE} = Plumber;   	# blows up
+    $SIG{PIPE} = "Plumber"; 	# just fine: quoted string is always ok
+    $SIG{PIPE} = \&Plumber; 	# preferred form
+
+=back
+
+See L<perlmodlib/Pragmatic Modules>.
+
+=head1 HISTORY
+
+C<strict 'subs'>, with Perl 5.6.1, erroneously permitted to use an unquoted
+compound identifier (e.g. C<Foo::Bar>) as a hash key (before C<< => >> or
+inside curlies), but without forcing it always to a literal string.
+
+Starting with Perl 5.8.1 strict is strict about its restrictions:
+if unknown restrictions are used, the strict pragma will abort with
+
+    Unknown 'strict' tag(s) '...'

+=head1 NAME
+
+vars - Perl pragma to predeclare global variable names (obsolete)
+
+=head1 SYNOPSIS
+
+    use vars qw($frob @mung %seen);
+
+=head1 DESCRIPTION
+
+NOTE: For variables in the current package, the functionality provided
+by this pragma has been superseded by C<our> declarations, available
+in Perl v5.6.0 or later.  See L<perlfunc/our>.
+
+This will predeclare all the variables whose names are 
+in the list, allowing you to use them under "use strict", and
+disabling any typo warnings.
+
+Unlike pragmas that affect the C<$^H> hints variable, the C<use vars> and
+C<use subs> declarations are not BLOCK-scoped.  They are thus effective
+for the entire file in which they appear.  You may not rescind such
+declarations with C<no vars> or C<no subs>.
+
+Packages such as the B<AutoLoader> and B<SelfLoader> that delay
+loading of subroutines within packages can create problems with
+package lexicals defined using C<my()>. While the B<vars> pragma
+cannot duplicate the effect of package lexicals (total transparency
+outside of the package), it can act as an acceptable substitute by
+pre-declaring global symbols, ensuring their availability to the
+later-loaded routines.
+
+See L<perlmodlib/Pragmatic Modules>.

+=head1 NAME
+
+warnings - Perl pragma to control optional warnings
+
+=head1 SYNOPSIS
+
+    use warnings;
+    no warnings;
+
+    use warnings "all";
+    no warnings "all";
+
+    use warnings::register;
+    if (warnings::enabled()) {

+    }
+
+    if (warnings::enabled("void")) {

+
+    warnings::warnif("some warning");
+    warnings::warnif("void", "some warning");
+    warnings::warnif($object, "some warning");
+
+=head1 DESCRIPTION
+
+The C<warnings> pragma is a replacement for the command line flag C<-w>,
+but the pragma is limited to the enclosing block, while the flag is global.
+See L<perllexwarn> for more information.
+
+If no import list is supplied, all possible warnings are either enabled
+or disabled.
+
+A number of functions are provided to assist module authors.
+
+=over 4
+
+=item use warnings::register
+
+Creates a new warnings category with the same name as the package where
+the call to the pragma is used.
+
+=item warnings::enabled()
+
+Use the warnings category with the same name as the current package.
+
+Return TRUE if that warnings category is enabled in the calling module.
+Otherwise returns FALSE.
+
+=item warnings::enabled($category)
+
+Return TRUE if the warnings category, C<$category>, is enabled in the
+calling module.
+Otherwise returns FALSE.
+
+=item warnings::enabled($object)
+
+Use the name of the class for the object reference, C<$object>, as the
+warnings category.
+
+Return TRUE if that warnings category is enabled in the first scope
+where the object is used.
+Otherwise returns FALSE.
+
+=item warnings::warn($message)
+
+Print C<$message> to STDERR.
+
+Use the warnings category with the same name as the current package.
+
+If that warnings category has been set to "FATAL" in the calling module
+then die. Otherwise return.
+
+=item warnings::warn($category, $message)
+
+Print C<$message> to STDERR.
+
+If the warnings category, C<$category>, has been set to "FATAL" in the
+calling module then die. Otherwise return.
+
+=item warnings::warn($object, $message)
+
+Print C<$message> to STDERR.
+
+Use the name of the class for the object reference, C<$object>, as the
+warnings category.
+
+If that warnings category has been set to "FATAL" in the scope where C<$object>
+is first used then die. Otherwise return.
