moss_getgroups — Construct groups out of the matched pairs returned by moss
The parameter is either a URL or, more likely, a file on the local filesystem such as one created by redirecting the output of moss_makereadable.
The program will read the URL or file specified. It will then examine all of the pairs of students in that file and organize them into collaborating groups, which are then printed to standard output as a list of groups, one per line, in sorted order. This script is useful after printouts have been made and the paper output is being examined.
