Hello, lately I have been doing some serious cleanup/dissection work on the ghemical app, and today I finally added the result back into CVS. At bioinformatics.org site CVS there now is a new module called liboglappth ; the HEAD version now depends on this. I have moved into liboglappth most the OpenGL-related aspects of the ghemical-app, so that those are more easily accessible on other programs as well. Using the library it is (or later will be) easy to build portable applications that mostly use OpenGL to display their information (menus and dialog boxes still need to be make in their platform-dependent ways tough). The HEAD version of the ghemical app is now assigned a version number 2.50, but still it very much a work-in-progress. It should compile now, and run, and the mouse tools should work so that one can draw and display molecules. Nothing else really works yet... The HEAD version looks just the same as the VERSION_2_BRANCH app, so the changes are invisible to the user. Regards, Tommi
