There is no long term planned feature set for astLib. Contributions of self-contained procedures and/or extra modules would be welcomed (feel free to contact me at mattyowl at users.sourceforge.net) - otherwise, features are likely to be added as and when they are required in the course of my work (or if I feel like implementing them).
Note the latest development version in the subversion repository can be obtained by doing:
> svn co https://astlib.svn.sourceforge.net/svnroot/astlib/trunk astlib
at the console.
