This folder once contained a Trinity-specific copy of the following projects: SIP PyQt PyKDE As SIP and PyQt are maintained upstream, a local copy for the Trinity project is not needed. Furthermore, the copy that once resided here was outdated and did not compile with the latest flex/bison/python sources.
