Oh - and please also add to the PKGBUILD:

optdepends=('inkscape: for viewing the generated graph')

"svg" is the default format and inkscape makes a convenient viewer.

Please update PKGBUILD, patch codecgraph.py for python version 3, and show python dependency in the AUR:

You might want to regenerate the diff file and run "updpkgsums" on the PKGBUILD to get the md5sum for the diff file. The proper diff file lines are suppose to begin with tabs, not spaces. Or "-l" could be added to the patch command.

bump to 20120104
