Revision 2327 - (show annotations) (download) (as text)
Wed Dec 22 07:17:24 2010 UTC (8 years, 11 months ago) by jpye
File MIME type: text/x-c++src
File size: 2355 byte(s)
Merging in refactor of the C++ code, which is moved out of 'pygtk' and into 'ascxx'.
Adding support for IPOPT 3.9.1, the current latest version.
Support in dtar for parallel builds (possibly needs some testing still).
