It is still a bit rough around some edges, particularly with regard to multi-threading and operator overloading, and there are some documentation bits missing, but it should be fine for basic use. The test-suite should build and run fine with the current versions of DMD, LDC and Tango (at least) on Linux x86_64 and Mac OS X 10.6. git-svn-id: https://swig.svn.sourceforge.net/svnroot/swig/trunk@12299 626c5289-ae23-0410-ae9c-e8d60b6d4f22
