Decided to go another route that doesn't require a readme.txt parser so deleting it.
Added initial classes for interfacing with version control systems: Git and Hg.
Included the VCS base files and switched to a named autoloader using spl_autoload_register();
Added errors and messages to WPPM_Command base class.
Added an out() method to Vcs_Agent and Hg_Agent and incorporated results of out() into is_clean().
Added a WPPM_License class to capture license info from the wp-package.json file.
Added, renamed and reroutes some properties in WPPM_Package.
Added functionality for WPPM_Status_Command->execute() to verify the status. Basically it checks to see if everything is in order before publishing the plugin.  This code will likely evolve a lot before we finalize this project.
Added a $FILEPATH property to WPPM_Container which was using in WPPM_Package.
Added a add_notice() method to WPPM_Command and fiddled around with some formatting.
Added, renamed and restructured several properties in the wp-package.json file.
