Hello again. I just made the 3rd "preview" version of mine available; not much has changed except much cleanup/janitorial work has been done, and I have converted the geometry optimization dialog into a libglade based one (Ok, that's not working yet, it only opens but the libglade system seems to be a promising one). Now there is a new directory target3/glade that also contains code for dialogs. Ok, the "preview" stuff seems to stabilize so that the filenames are not changing anymore; therefore I will probably add the next week's "preview" to CVS at bioinformatics.org. I will absolutely not replace the current version, but just bring the "preview" in as an alternative version using CVS "branching". Then the both versions are available at CVS. In the "CVS book" there is a good description about branches: http://cvsbook.red-bean.com/cvsbook.html#Branches I'll tell more about the details next week. Good weekends, Tommi
