I haven't seen many scripts posted lately, and here's one which I find quite useful, so here goes. I'll probably add some features like a merge flag to merge the perl tags with whatever tags are already in the tags file, and possibly a flag to automatically create tags for all 'required' files aswell. Anyway, here's an early release.
Tags file containing a sorted list of tags, one tag per line.
Merge with existing tags file. Name of tags file to create. Include variable definitions. List of files to scan for tags. Merge new tags with existing tags.
