[SVN commits to the Asterisk project]

Author: dlee

New Revision: 392402

URL: http://svnview.digium.com/svn/asterisk?view=rev&rev=392402
Log:
make ari-stubs: only overwrite files when they change.

This helps a tiny bit with useless rebuilds, but also helps make the build
a bit less noisy when you're just changing one file.
