Subject: Alternatively accept files from command line arguments in elfdeps
X-Git-Tag: tznext/4.11.0.1.tizen20130304~110
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=41702fa154ad1fdf8a54aa5642f0a572ecfe123b;p=tools%2Flibrpm-tizen.git

Alternatively accept files from command line arguments in elfdeps

- Nothing actually needs this, but for testing & debugging command line
  args are often nicer than having to pass stuff via stdin.
(cherry picked from commit 6941d51e7e5139014418d1056acb6dafccefbab7)
