2005-05-07 Thread for_spam
Hello, just for your information - there is a commercially "branded" UML out now (don`t know for how long, but I came across stinghorn today): http://www.stinghorn.com/opensource/ I thought it was worth mentioning, because there is no reference to "stinghorn" on the website or in the ML archive

[uml-devel] Generating patches with --show-c-functions

2005-05-07 Thread Blaisorblade
