Okay, well here's a script for the first item.  The 'XDG Base Directory
Spec' tells where to look up the .desktop file, so looks like you just
iterate over a few dirs and look for the file.

The idea is that you'd run rpm -i or autopackage or Klik or apt-get or
make install or whatever to install your app, then call this script to
check if it installed its .desktop file in the proper location.  You
probably would want to call this ahead of time to check that the app
wasn't already installed.

The script is attached below.  Examples of usage:

  $ ./xdg_lookup_file -D applications/inkscape.desktop
  /usr/local/share/applications/inkscape.desktop

  $ ./xdg_lookup_file -D applications/kde-xmms.desktop

  $ ./xdg_lookup_file -d applications/kde-xmms.desktop
  /home/bryce/.local/share/applications/kde-xmms.desktop

  $ ./xdg_lookup_file -C menus/applications.menu
  /etc/xdg/menus/applications.menu

-D searches the system XDG data dir (only), -d searches the user XDG
data dir as well as the system dir.  -C and -c do the same thing but
search the config dirs.  In any case, it returns 0 if it found
something, 1 if it didn't, and -1 on error.

You could also probably use this to test that the app uninstalled itself
properly.  (I hate it when I uninstall an app and it leaves bits of
itself in my menu system...)
