=head1 NAME

App::Git::Workflow - Git workflow tools

=head1 VERSION

This documentation refers to App::Git::Workflow version 1.1.20

=head1 SYNOPSIS

   use App::Git::Workflow qw/branches tags/;

   # Get all local branches
   my @branches = $self->branches();
   # or
   @branches = $self->branches('local');

   # remote branches
   @branches = $self->branches('remote');

   # both remote and local branches
   @branches = $self->branches('both');

   # similarly for tags
   my @tags = $self->tags();

=head1 DESCRIPTION

This module contains helper functions for the command line scripts.

=head1 SUBROUTINES/METHODS

=head2 C<new (%params)>

Create a new C<App::Git::Workflow::Pom> object

=head2 C<git ()>

Get the git repository object

=head2 C<branches ([ $type ])>

Param: C<$type> - one of local, remote or both

Returns a list of all branches of the specified type. (Default type is local)

=head2 C<tags ()>

Returns a list of all tags.

=head2 C<_alphanum_sort ()>

Does sorting (for the building C<sort>) in a alpha numerical fashion.
Specifically all numbers are converted for the comparison to 14 digit strings
with leading zeros.

=head2 C<children ($dir)>

Get the child files of C<$dir>

=head2 C<config ($name, $default)>

Get the git config value of C<$name>, or if not set C<$default>

Get the current branch/tag or commit

=head2 C<match_commits ($type, $regex, $max)>

=head2 C<release ($tag_or_branch, $local, $search)>

=head2 C<releases (%option)>

=head2 C<commit_details ($name)>

Get info from C<git show $name>

=head2 C<files_from_sha ($sha)>

Get the files changed by the commit

=head2 C<slurp ($file)>

Return the contents of C<$file>

=head2 C<spew ( $file, @data )>

Write C<@data> to the file C<$file>

=head2 C<settings ()>

Get the saved settings for the current repository

=head2 C<save_settings ()>
