           Summary: add JKII and JA support to OSX setup
           Product: GtkRadiant
           Version: 1.4
          Platform: All
        OS/Version: MacOS X
            Status: NEW
          Severity: normal
          Priority: P2
         Component: setup
        AssignedTo: ttimo@idsoftware.com
        ReportedBy: ttimo@idsoftware.com


As there are OSX ports of JKII and JA, we should provide game packs in the OSX
setup. The main tasks I'd think about to achieve that .. the .xml.in template
needs to have two game pack nodes added, and the osx_setup.py script needs to be
updated to fetch the right modules and the new ones.

You trigger the build of a .info file and it's associated tarball by doing
'scons BUILD=info'
