I have not had enough time to better document the user tools that I have written and posted on the Scriptorium at http://nwc-scriptorium.org/nwc2scripts.html
I'm slowly getting around to it, but have only done a few tools so far. Please have a look at
http://nwc-scriptorium.org/ftp/nwc2scripts/generaldiscussion.pdf
http://nwc-scriptorium.org/ftp/nwc2scripts/howtousethetripletisetool.pdf
http://nwc-scriptorium.org/ftp/nwc2scripts/global_mod.pdf
and
http://nwc-scriptorium.org/ftp/nwc2scripts/ccapm.pdf
(though note that ccapm.pdf might change - I'm thinking of some sort of delete-only option).
I'll be away for several weeks very soon. If there is something you desperately want documented, please let me know a.s.a.p. and I'll see if I can get it done before I go.
