This is an automated email from the git hooks/post-receive script.

tjaalton-guest pushed a commit to branch master
in repository libapache2-mod-nss.

commit 6286793e32535b2db1bc82398257a953ee36936f
Author: rcritten <>
Date:   Wed Jan 4 22:07:58 2006 +0000

    Changes to allow the mod_nss to work in Apache 2.2.0. Based on a patch
    from Oden Eriksson.
    
    The conditional to determine which API to use is a bit weak at the moment
    but it works with Apache 2.0.54 and 2.2.0.
