Tidying obsolete files

Summary

I've avoided "–delete" when rsynching to the server, so there are now lots of stray files there. Here is a plan to find and delete them without too high a risk of problems.

Plan

There's a new mode in makefile - find_strays.

This runs a "find" remotely, brings the results back, then runs find here.

Directories to do

• templates
• cgi-bin
• can_js
• pages/code
• plugins
• modules
