-Term::UI - Term::ReadLine UI made easy
-
-=head1 SYNOPSIS
-
-    use Term::UI;
-    use Term::ReadLine;
-
-    my $term = Term::ReadLine->new('brand');
-
-    my $reply = $term->get_reply(
-                    prompt => 'What is your favourite colour?',
-                    choices => [qw|blue red green|],
-                    default => 'blue',
-    );
-
-    my $bool = $term->ask_yn(
-                        prompt => 'Do you like cookies?',
-                        default => 'y',
-                );
-
-
-    my $string = q[some_command -option --no-foo --quux='this thing'];
-
-    my ($options,$munged_input) = $term->parse_options($string);
-
-
-    ### don't have Term::UI issue warnings -- default is '1'
-    $Term::UI::VERBOSE = 0;
-
-    ### always pick the default (good for non-interactive terms)
-    ### -- default is '0'
-    $Term::UI::AUTOREPLY = 1;
-
-    ### Retrieve the entire session as a printable string:
-    $hist = Term::UI::History->history_as_string;
-    $hist = $term->history_as_string;

-=head1 DESCRIPTION
-
-C<Term::UI> is a transparent way of eliminating the overhead of having
-to format a question and then validate the reply, informing the user
-if the answer was not proper and re-issuing the question.
-
-Simply give it the question you want to ask, optionally with choices
-the user can pick from and a default and C<Term::UI> will DWYM.
-
-For asking a yes or no question, there's even a shortcut.
-
-=head1 HOW IT WORKS
-
-C<Term::UI> places itself at the back of the C<Term::ReadLine>
-C<@ISA> array, so you can call its functions through your term object.
-
-C<Term::UI> uses C<Term::UI::History> to record all interactions
-with the commandline. You can retrieve this history, or alter
-the filehandle the interaction is printed to. See the
-C<Term::UI::History> manpage or the C<SYNOPSIS> for details.
-
-=head1 METHODS
-
-=head2 $reply = $term->get_reply( prompt => 'question?', [choices => \@list, default => $list[0], multi => BOOL, print_me => "extra text to print & record", allow => $ref] );
-
-C<get_reply> asks a user a question, and then returns the reply to the
-caller. If the answer is invalid (more on that below), the question will
-be reposed, until a satisfactory answer has been entered.
-
-You have the option of providing a list of choices the user can pick from
-using the C<choices> argument. If the answer is not in the list of choices
-presented, the question will be reposed.
-
-If you provide a C<default>  answer, this will be returned when either
-C<$AUTOREPLY> is set to true, (see the C<GLOBAL VARIABLES> section further
-below), or when the user just hits C<enter>.
-
-You can indicate that the user is allowed to enter multiple answers by
-toggling the C<multi> flag. Note that a list of answers will then be
-returned to you, rather than a simple string.
-
-By specifying an C<allow> hander, you can yourself validate the answer
-a user gives. This can be any of the types that the Params::Check C<allow>
-function allows, so please refer to that manpage for details.
-
-Finally, you have the option of adding a C<print_me> argument, which is
-simply printed before the prompt. It's printed to the same file handle
-as the rest of the questions, so you can use this to keep track of a
-full session of Q&A with the user, and retrieve it later using the
-C<< Term::UI->history_as_string >> function.
-
-See the C<EXAMPLES> section for samples of how to use this function.

-=head2 ($opts, $munged) = $term->parse_options( STRING );
-
-C<parse_options> will convert all options given from an input string
-to a hash reference. If called in list context it will also return
-the part of the input string that it found no options in.
-
-Consider this example:
-
-    my $str =   q[command --no-foo --baz --bar=0 --quux=bleh ] .
-                q[--option="some'thing" -one-dash -single=blah' arg];
-
-    my ($options,$munged) =  $term->parse_options($str);
-
-    ### $options would contain: ###
-    $options = {
-                'foo'       => 0,
-                'bar'       => 0,
-                'one-dash'  => 1,
-                'baz'       => 1,
-                'quux'      => 'bleh',
-                'single'    => 'blah\'',
-                'option'    => 'some\'thing'
-    };
-
-    ### and this is the munged version of the input string,
-    ### ie what's left of the input minus the options
-    $munged = 'command arg';
-
-As you can see, you can either use a single or a double C<-> to
-indicate an option.
-If you prefix an option with C<no-> and do not give it a value, it
-will be set to 0.
-If it has no prefix and no value, it will be set to 1.
-Otherwise, it will be set to its value. Note also that it can deal
-fine with single/double quoting issues.

-
-This holds the string that will be printed when the user makes an

-                default => 'blue' );
-
-which would look like:
-
-      1> red
-      2> green
-      3> blue
-
-    Your favourite colour? [3]:
-
-Note the default answer after the prompt. A user can now just hit C<enter>
-(or set C<$Term::UI::AUTOREPLY> -- see the C<GLOBAL VARIABLES> section) and
-the sensible answer 'blue' will be returned.

-=head2 get_reply using print_me & multi
-
-    ### allow the user to pick more than one colour and add an
-    ### introduction text
-    @reply = $term->get_reply(
-                print_me    => 'Tell us what colours you like',
-                prompt      => 'Your favourite colours?',
-                choices     => [qw|red green blue|],
-                multi       => 1 );
-
-which would look like:
-
-    Tell us what colours you like
-      1> red
-      2> green
-      3> blue
-
-    Your favourite colours?
-
-An answer of C<3 2 1> would fill C<@reply> with C<blue green red>
-
-=head2 get_reply & allow
-
-    ### pose an open question, but do a custom verification on
-    ### the answer, which will only exit the question loop, if
-    ### the answer matches the allow handler.
-    $reply = $term->get_reply(
-                prompt  => "What is the magic number?",
-                allow   => 42 );
-
-Unless the user now enters C<42>, the question will be reposed over
-and over again. You can use more sophisticated C<allow> handlers (even
-subroutines can be used). The C<allow> handler is implemented using
-C<Params::Check>'s C<allow> function. Check its manpage for details.
-
-=head2 an elaborate ask_yn sample
-
-    ### ask a user if he likes cookies. Default to a sensible 'yes'
-    ### and inform him first what cookies are.
-    $bool = $term->ask_yn( prompt   => 'Do you like cookies?',
-                           default  => 'y',
-                           print_me => 'Cookies are LOVELY!!!' );
-
-would print:
-
-    Cookies are LOVELY!!!
-    Do you like cookies? [Y/n]:
-
-If a user then simply hits C<enter>, agreeing with the default,
-C<$bool> would be set to C<true>. (Simply hitting 'y' would also
-return C<true>. Hitting 'n' would return C<false>)
-
-We could later retrieve this interaction by printing out the Q&A
-history as follows:
-
-    print $term->history_as_string;
-
-which would then print:
-
-    Cookies are LOVELY!!!
-    Do you like cookies? [Y/n]:  y
-
-There's a chance we're doing this non-interactively, because a console
-is missing, the user indicated he just wanted the defaults, etc.
-
-In this case, simply setting C<$Term::UI::AUTOREPLY> to true, will
-return from every question with the default answer set for the question.
-Do note that if C<AUTOREPLY> is true, and no default is set, C<Term::UI>
-will warn about this and return C<undef>.
