I meant to post this earlier, but I've had my head stuck in reference manuals, code, and Makefiles, and lost track of the calendar ...
The Homespun Ceilidh Band will be performing at the Greenbelt Arts Center this Friday, 2011-04-08, at 8:00 PM. General admission $15; students/seniors $12. Call 301-441-8770 for reservations.
There's a flier with the same info and a photo of the band, to print out and put up on bulletin boards where you're allowed to post such things, or to give to interested friends.
And now back to banging on this program that I hope to have in a show-off-ready state soonish. The documentation is taking more time than the code, of course, but the code isn't really finished until the documentation is done.
