I had a look on this some month ago because I thought it could help me to solve some problem I had. I gave up on this direction and only took a little time to think about encapsulating some_pack routines in a C++ class that would talk easily with ROOT classes. The conception of the SOM_PACK programm is very nice for shell interaction (lots of small independant programms) but is a source of complications when wanting to desing a single API to interact with. I thought that the fastest (but not the nicest) path would be to keep this as is, leaving the routines writing a file read by the next one and so on. So you only have to care about generating the input file from root and reading the last output one into root (read/write on file is very slow, but as those routines are very computer intensive, in most cases it's not the bottleneck). For me, any other approach would requier a lot of rewriting in the SOM_PACK programm (maybe enough to justify a reimplementation from scratch). Anyway, I didnt went very far as I didnt used it at the end, but I would be interested if you did anything in this direction. Yannick
