NAME
    Perinci::CmdLine::Easy - A simple interface to run a subroutine as
    command-line app

VERSION
    This document describes version 1.16 of Perinci::CmdLine::Easy (from
    Perl distribution Perinci-CmdLine-Easy), released on 2014-07-03.

SYNOPSIS
    In your command-line script (e.g. named list-cpan-dists):

     use JSON qw(decode_json);
     use LWP::Simple;
     use Perinci::CmdLine::Easy qw(run_cmdline_app);
     run_cmdline_app(
         summary => "List CPAN distributions that belong to an author",
         sub     => sub {
             my $cpanid = shift or die "Please supply CPAN ID\n";
             my $res = get "http://api.metacpan.org/v0/release/_search?q=author:".
                 uc($cpanid)."%20AND%20status:latest&fields=name&size=5000"
                 or die "Can't query MetaCPAN";
             $res = $json->decode($res);
             die "MetaCPAN timed out\n" if $res->{timed_out};
             my @dists;
             for my $hit (@{ $res->{hits}{hits} }) {
                 my $dist = $hit->{fields}{name};
                 $dist =~ s/-\d.+//;
                 push @dists, $dist;
             }
             \@dists;
         },
         argv    => [qw/cpanid*/],
     );

    To run this program:

     % list-cpan-dists --help ;# display help message
     % LANG=id_ID list-cpan-dists --help ;# display help message in Indonesian
     % list-cpan-dists SHARYANTO

    To do bash tab completion:

     % complete -C list-cpan-dists list-cpan-dists
     % list-cpan-dists <tab> ;# completes to --help, --version, --cpanid, etc
     % list-cpan-dists --c<tab> ;# completes to --cpanid

DESCRIPTION
    Perinci::CmdLine::Easy provides an easier alternative to
    Perinci::CmdLine. You do not need to know any Rinci or Riap concepts, or
    provide your own metadata. Just supply the subroutine, summary, list of
    arguments, and you're good to go. Of course, if you need more
    customization, there's Perinci::CmdLine.

    What you'll get:

    *   Command-line options parsing

    *   Help message (supports translation)

    *   Tab completion for bash

    *   Formatting of output (supports complex data structure)

    *   Logging

FUNCTIONS
  run_cmdline_app(%args) -> any
    A simple interface to run a subroutine as command-line app.

    Arguments ('*' denotes required arguments):

    *   argv => *array* (default: [])

        List of arguments.

        Each argument is NAME, NAME* (marking required argument), or NAME+
        (marking greedy argument, where the rest of command-line arguments
        will be fed into this array).

    *   description => *str*

    *   sub* => *any*

        Coderef or subroutine name.

    *   summary => *str*

    Return value:
