+=head1 NAME
+
+File::Spec - portably perform operations on file names
+
+=head1 SYNOPSIS
+
+ use File::Spec;
+
+ $x=File::Spec->catfile('a', 'b', 'c');
+
+which returns 'a/b/c' under Unix. Or:
+
+ use File::Spec::Functions;
+
+ $x = catfile('a', 'b', 'c');
+
+=head1 DESCRIPTION
+
+This module is designed to support operations commonly performed on file
+specifications (usually called "file names", but not to be confused with the
+contents of a file, or Perl's file handles), such as concatenating several
+directory and file names into a single path, or determining whether a path
+is rooted. It is based on code directly taken from MakeMaker 5.17, code
+written by Andreas KE<ouml>nig, Andy Dougherty, Charles Bailey, Ilya
+Zakharevich, Paul Schinder, and others.
+
+Since these functions are different for most operating systems, each set of
+OS specific routines is available in a separate module, including:
+
+ File::Spec::Unix
+ File::Spec::Mac
+ File::Spec::OS2
+ File::Spec::Win32
+ File::Spec::VMS
+
+The module appropriate for the current OS is automatically loaded by
+File::Spec. Since some modules (like VMS) make use of facilities available
+only under that OS, it may not be possible to load all modules under all
+operating systems.
+
+Since File::Spec is object oriented, subroutines should not be called directly,
+as in:
+
+ File::Spec::catfile('a','b');
+
+but rather as class methods:
+
+ File::Spec->catfile('a','b');
+
+For simple uses, L<File::Spec::Functions> provides convenient functional
+forms of these methods.
+
+=head1 METHODS
+
+=over 2
+
+=item canonpath
+
+No physical check on the filesystem, but a logical cleanup of a
+path.
+
+ $cpath = File::Spec->canonpath( $path ) ;
+
+Note that this does *not* collapse F<x/../y> sections into F<y>. This
+is by design. If F</foo> on your system is a symlink to F</bar/baz>,
+then F</foo/../quux> is actually F</bar/quux>, not F</quux> as a naive
+F<../>-removal would give you. If you want to do this kind of
+processing, you probably want C<Cwd>'s C<realpath()> function to
+actually traverse the filesystem cleaning up paths like this.
+
+=item catdir
+
+Concatenate two or more directory names to form a complete path ending
+with a directory. But remove the trailing slash from the resulting
+string, because it doesn't look good, isn't necessary and confuses
+OS/2. Of course, if this is the root directory, don't cut off the
+trailing slash :-)
+
+ $path = File::Spec->catdir( @directories );
+
+=item catfile
+
+Concatenate one or more directory names and a filename to form a
+complete path ending with a filename
+
+ $path = File::Spec->catfile( @directories, $filename );
+
+=item curdir
+
+Returns a string representation of the current directory.
+
+ $curdir = File::Spec->curdir();
+
+=item devnull
+
+Returns a string representation of the null device.
+
+ $devnull = File::Spec->devnull();
+
+=item rootdir
+
+Returns a string representation of the root directory.
+
+ $rootdir = File::Spec->rootdir();
+
+=item tmpdir
+
+Returns a string representation of the first writable directory from a
+list of possible temporary directories. Returns the current directory
+if no writable temporary directories are found. The list of directories
+checked depends on the platform; e.g. File::Spec::Unix checks C<$ENV{TMPDIR}>
+(unless taint is on) and F</tmp>.
+
+ $tmpdir = File::Spec->tmpdir();
+
+=item updir
+
+Returns a string representation of the parent directory.
+
+ $updir = File::Spec->updir();
+
+=item no_upwards
+
+Given a list of file names, strip out those that refer to a parent
+directory. (Does not strip symlinks, only '.', '..', and equivalents.)
+
+ @paths = File::Spec->no_upwards( @paths );
+
+=item case_tolerant
+
+Returns a true or false value indicating, respectively, that alphabetic
+case is not or is significant when comparing file specifications.
+
+ $is_case_tolerant = File::Spec->case_tolerant();
+
+=item file_name_is_absolute
+
+Takes as its argument a path, and returns true if it is an absolute path.
+
+ $is_absolute = File::Spec->file_name_is_absolute( $path );
+
+This does not consult the local filesystem on Unix, Win32, OS/2, or
+Mac OS (Classic). It does consult the working environment for VMS
+(see L<File::Spec::VMS/file_name_is_absolute>).
+
+=item path
+
+Takes no argument. Returns the environment variable C<PATH> (or the local
+platform's equivalent) as a list.
+
+ @PATH = File::Spec->path();
+
+=item join
+
+join is the same as catfile.
+
+=item splitpath
+
+Splits a path in to volume, directory, and filename portions. On systems
+with no concept of volume, returns '' for volume.
+
+ ($volume,$directories,$file) = File::Spec->splitpath( $path );
+ ($volume,$directories,$file) = File::Spec->splitpath( $path, $no_file );
+
+For systems with no syntax differentiating filenames from directories,
+assumes that the last file is a path unless C<$no_file> is true or a
+trailing separator or F</.> or F</..> is present. On Unix, this means that C<$no_file>
+true makes this return ( '', $path, '' ).
+
+The directory portion may or may not be returned with a trailing '/'.
+
+The results can be passed to L</catpath()> to get back a path equivalent to
+(usually identical to) the original path.
+
+=item splitdir
+
+The opposite of L</catdir()>.
+
+ @dirs = File::Spec->splitdir( $directories );
+
+C<$directories> must be only the directory portion of the path on systems
+that have the concept of a volume or that have path syntax that differentiates
+files from directories.
+
+Unlike just splitting the directories on the separator, empty
+directory names (C<''>) can be returned, because these are significant
+on some OSes.
+
+=item catpath()
+
+Takes volume, directory and file portions and returns an entire path. Under
+Unix, C<$volume> is ignored, and directory and file are concatenated. A '/' is
+inserted if need be. On other OSes, C<$volume> is significant.
+
+ $full_path = File::Spec->catpath( $volume, $directory, $file );
+
+=item abs2rel
+
+Takes a destination path and an optional base path returns a relative path
+from the base path to the destination path:
+
+ $rel_path = File::Spec->abs2rel( $path ) ;
+ $rel_path = File::Spec->abs2rel( $path, $base ) ;
+
+If C<$base> is not present or '', then L<cwd()|Cwd> is used. If C<$base> is
+relative, then it is converted to absolute form using
+L</rel2abs()>. This means that it is taken to be relative to
+L<cwd()|Cwd>.
+
+On systems with the concept of volume, if C<$path> and C<$base> appear to be
+on two different volumes, we will not attempt to resolve the two
+paths, and we will instead simply return C<$path>. Note that previous
+versions of this module ignored the volume of C<$base>, which resulted in
+garbage results part of the time.
+
+On systems that have a grammar that indicates filenames, this ignores the
+C<$base> filename as well. Otherwise all path components are assumed to be
+directories.
+
+If C<$path> is relative, it is converted to absolute form using L</rel2abs()>.
+This means that it is taken to be relative to L<cwd()|Cwd>.
+
+No checks against the filesystem are made. On VMS, there is
+interaction with the working environment, as logicals and
+macros are expanded.
+
+Based on code written by Shigio Yamaguchi.
+
+=item rel2abs()
+
+Converts a relative path to an absolute path.
+
+ $abs_path = File::Spec->rel2abs( $path ) ;
+ $abs_path = File::Spec->rel2abs( $path, $base ) ;
+
+If C<$base> is not present or '', then L<cwd()|Cwd> is used. If C<$base> is relative,
+then it is converted to absolute form using L</rel2abs()>. This means that it
+is taken to be relative to L<cwd()|Cwd>.
+
+On systems with the concept of volume, if C<$path> and C<$base> appear to be
+on two different volumes, we will not attempt to resolve the two
+paths, and we will instead simply return C<$path>. Note that previous
+versions of this module ignored the volume of C<$base>, which resulted in
+garbage results part of the time.
+
+On systems that have a grammar that indicates filenames, this ignores the
+C<$base> filename as well. Otherwise all path components are assumed to be
+directories.
+
+If C<$path> is absolute, it is cleaned up and returned using L</canonpath()>.
+
+No checks against the filesystem are made. On VMS, there is
+interaction with the working environment, as logicals and
+macros are expanded.
+
+Based on code written by Shigio Yamaguchi.

+On systems that have a grammar that indicates filenames, this ignores
+the $base filename. Otherwise all path components are assumed to be
+directories.
+
+If $path is absolute, it is cleaned up and returned using L</canonpath()>.
+
+No checks against the filesystem are made. On VMS, there is
+interaction with the working environment, as logicals and
+macros are expanded.

+Based on code written by Shigio Yamaguchi.

+
+=head1 SYNOPSIS
+
+ require File::Spec::Win32; # Done internally by File::Spec if needed
+
+=head1 DESCRIPTION
+
+See File::Spec::Unix for a documentation of the methods provided
+there. This package overrides the implementation of these methods, not
+the semantics.

+
+Returns a string representation of the null device.

+
+sub devnull {

+sub rootdir () { '\\' }
+
+
+=item tmpdir
+
+Returns a string representation of the first existing directory
+from the following list:
+
+ $ENV{TMPDIR}
+ $ENV{TEMP}
+ $ENV{TMP}
+ SYS:/temp
+ C:\system\temp
+ C:/temp
+ /tmp
+ /
+
+The SYS:/temp is preferred in Novell NetWare and the C:\system\temp
+for Symbian (the File::Spec::Win32 is used also for those platforms).
+
+Since Perl 5.8.0, if running under taint mode, and if the environment
+variables are tainted, they are not used.

+
+No physical check on the filesystem, but a logical cleanup of a
+path. On UNIX eliminated successive slashes and successive "/.".
+On Win32 makes

+ dir1\dir2\dir3\..\..\dir4 -> \dir\dir4 and even

+=item splitpath
+
+ ($volume,$directories,$file) = File::Spec->splitpath( $path );
+ ($volume,$directories,$file) = File::Spec->splitpath( $path, $no_file );
+
+Splits a path into volume, directory, and filename portions. Assumes that
+the last file is a path unless the path ends in '\\', '\\.', '\\..'
+or $no_file is true. On Win32 this means that $no_file true makes this return
+( $volume, $path, '' ).
+
+Separators accepted are \ and /.
+
+Volumes can be drive letters or UNC sharenames (\\server\share).
+
+The results can be passed to L</catpath> to get back a path equivalent to
+(usually identical to) the original path.

+=item splitdir
+
+The opposite of L<catdir()|File::Spec/catdir()>.
+
+ @dirs = File::Spec->splitdir( $directories );
+
+$directories must be only the directory portion of the path on systems
+that have the concept of a volume or that have path syntax that differentiates
+files from directories.
+
+Unlike just splitting the directories on the separator, leading empty and
+trailing directory entries can be returned, because these are significant
+on some OSs. So,
+
+ File::Spec->splitdir( "/a/b/c" );
+
+Yields:
+
+ ( '', 'a', 'b', '', 'c', '' )
