NAME

Dist::Mgr - Automation for Perl distribution creation, integration, pre-release, release and post-release tasks.

Coverage Status

DESCRIPTION

For end-users, please review the documentation for the distmgr program that we've installed for you as part of this distribution.

This software performs a full suite of automated creation, addition, pre-release, release and post release tasks for Perl distributions. It integrates with VCS, automates the configuration of Continuous Integration, manages version numbers and Changes files, amongst a slew of other tasks.

This distribution is essentially a bunch of tools that revolve around a base distribution created with module-starter.

At this time, it relies on using Module::Starter for initial distribution creation, Github for repository and bugtracker, and the ExtUtils::MakeMaker build system, which utilizes Makefile.PL files.

SYNOPSIS

    use Dist::Mgr qw(:all)

    ...

EXPORT_OK

We do not automatically import anything into your namespace, you must request functionality explicitly. Use the :all tag, or have a peruse through the "FUNCTIONS" section for what's available.
