Expat is included on OSX. All that is needed by gpsbabel beyond the system expat is the xmlwf command to build the docs. Tried to make the docs build work but even with expat and docbook dependencies they don't seem to build.
* Use new "url" features
* Use keg_only DSL
* Use "skip_clean :all" DSL
* Whitespace and style cleanups
* Make bash invocations less silly
* Use new man2-man8 helpers
* Remove "FileUtils." since it is included in Formula
* Use real names for deps instead of aliases
* ENV.x11 now updates path, so remove that from individual brews
Gpsbabel <http://www.gpsbabel.org> converts waypoints, tracks, and routes between popular GPS receivers and mapping programs. It also has powerful manipulation tools for such data.
