retire.py

#!/usr/bin/env python3

"""

Script to create retirement files for a project.

Input:
- https://whimsy.apache.org/public/committee-retired.json
- https://lists.apache.org/api/preferences.lua
- xdocs/projects/_template.xml
- _template.jira

Output:
- xdocs/flagged/<pid> (created)
- xdocs/projects/<pid>.xml (created)
- xdocs/stylesheets/project.xml (updated)
- <pid>.jira.tmp (created) - this is for pasting into an Attic JIRA issue

N.B. The generated pid.xml file may need tweaking
