The .rules files provided with the distribution aren't recognized by VS2010, and I'd really like to avoid having to write a whole MSBuild task and all that for what should be a simple tool.
Currently I've been using the pre-build event and making the commandline manually... but that kind of sucks when there's more than one grammar to worry about.
EDIT: Since the only answer is my own, and I don't want to be a point whore, I've made this CW.
