 Description: Make the Python CMake scripts more versatile in version handling.
  The FindPython{Interp,Libs}.cmake scripts need to cater for a set version or,
  failing that, in Debian, set the default version for Python in Debian.
+ As a last resort we still try a list of hardcoded values.
  .
  This patch addresses both issues. (Closes: #569321, #580503)
  .
- Parts of this patch were sent upstream (the "request a specific version" part).
- The part for requesting a specific version was written by Didier Raboud
- <didier@raboud.com>.
+ Parts of this patch were based on Didier Raboud's <didier@raboud.com> patch for
+ #569321.
