X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=e4a9f366dbcb54f76b8c42869fa6873808132357;p=inkscape.git

 r19076@shi:  ted | 2008-04-21 15:42:45 -0700
 Core of having a real namespace for Inkscape extensions.
 r19077@shi:  ted | 2008-04-21 15:50:12 -0700
 First layer of adding NS
 r19078@shi:  ted | 2008-04-21 15:56:03 -0700
 Whew, doing the rest of them.
