This is a simple script that dumps the groups, and optionally the weights, of selected vertices on a mesh. Its likely to only run on 2.34 without changes though, so grab a test build if you aren’t working with a CVS build already or wait until 2.34 is released.
The script can be found http://www.visi.com/~zaz/vertexGroups.py for download or for posterity in the code block below.
Since this is so trivial, it is released without restriction, do with it as you wish.
