I've been using git submodule to refer to external repos that I don't maintain. (which works great)
So far in order to use an svn repo as a submodule I end up doing a git svn clone, and basically have a crontab job that pulls from svn and pushes to git repo. Then I end up using the git repo it creates as a git submodule.
The workflow does work, though it is a bit tedious. I was wondering if there was any particular reason why having an svn repo as a submodule isn't supported at this time. Or if there was a better way of accomplishing this that escapes me.
