[xtag-meeting]: Meetings will be on FRIDAYS

The first important announcement is that the meetings during the rest
of the summer will be on -- Friday -- 10:30 a.m. same place as usual

This Friday, Jul 19, we will be discussing some final(?)/finer-grained
details of the implementation of the new XTAG development environment:
e.g., grammar editing and automatic generation via metarules.
