ming-linux.patch.gz: patch to compile with g++

also interesting, is MIN, “The Earlier Version Of MING”

http://www.math.uiowa.edu/~wu/min/min.html

non graphical version of the energy minimser code that supposedly compiles on unix, although i suspect it will need similar massaging as above to compile with g++. may be useful for study.
