"""
The package header is a YAML file that is used by the ROS.org wiki as
well as rosinstall.  It is similar in concept to the package manifest
(manifest.xml), but it contains additional data and is in YAML format
for easier processing in python scripts.

The data in the package header is not formally specified, but includes:

 * manifest data (description, license, author, depends, review status, url)
 * rosinstall configuration information (VCS URI, branches, etc...)
 * stack and stack siblings (packages)
 * depends-on information
 * msg/srv listing
