Mike, All, On 2013-08-12 19:36 -0400, Mike Pagano spake thusly: > Modification of the diffconfig script to support python versions 2.6 and > greater. Added a small change to gracefully exit if the default config files > are not present. (.config and .config.old) Please, send two patches: - one with fixes for python 2.6+ - one with the check for config files Regards, Yann E.
