[ragel-users] [PATCH 3/6] Make it possible to enable/disable parsers generation at ./configure

[Adrian Thurston]

I don't see why anyone would need to use this. Either you're doing 
development on ragel and you're working out of SVN or you're grabbing a 
release for building and installing. Maybe someone might want to do 
development on an older version but I think that would be pretty rare.
