Subject: Perform dependency extraction solely based on collected attributes
X-Git-Tag: tznext/4.11.0.1.tizen20130304~2296
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=0e36eb1370e4e856a337460a2d69de4288aed77b;p=tools%2Flibrpm-tizen.git

Perform dependency extraction solely based on collected attributes
- Yank out the now unnecessary apply table + related apply functions, simply
  collect dependencies for whatever attributes we found for a given file
