[pacman-dev] Script to validate ABS/PKGBUILDs

[Scott Horowitz]

After reading Xavier's email[1] that mentioned the possibility of an
external script to check for circular dependencies, I set out to do
just that. Along the way, I found a number of other issues in the ABS
tree and decided to report those out as well.

The script is written in python because dicts make it all so much
easier. It takes a little over a minute to run on my 1.5ghz machine.
>From the script itself:

#  This script currently checks for a number of issues in your ABS
#  tree:
#    1. Directories with missing PKGBUILDS
#    2. Duplicate PKGBUILDs
#    3. Referenced dependencies (and make-dependencies) that cannot
#       be found. This correctly takes into account any 'provides'.
#    4. Circular dependencies
#
# Todo:
#    1. Account for versioned deps, e.g., foo=1.2.3
#    2. Accommodate testing repo?

Hopefully people find it useful. I'm open to suggestions and improvements.

WARNING: Please make sure you have a clean $ABSROOT when running this
         script; custom PKGBUILDs, etc. can cause false positives.
