"""
Scans apps dir for application versions
and updates the database as appropriate.
config.xml must contain an <app_dir> which specifies the directory to search.
apps/APPLICATION_NAME/ contains application versions for each application.
Filenames must be of the form NAME_VERSION_PLATFORM[.ext].
The prefix name and extensions .gz, .exe, .sit are ignored.
Platform strings must match the names of platforms in the database.
update_versions also handles subdirectories,
which contain files to bundle as a single app-version.
Subdirectory names are ignored.
Non-executable files can be arbitrarily named.
Example setup:
apps/boinc/boinc_7.17_i686-pc-linux-gnu.gz
apps/Astropulse/astropulse_7.17_windows_intelx86.exe
apps/SETI@home/sah_4.20_sparc-sun-solaris2.9.gz
apps/SETI@home/sah_4.20_i686-pc-linux-gnu.gz
apps/SETI@Home/sah_4.21_sparc-sun-solaris2.9/sah_4.21_sparc-sun-solaris2.9.gz
