Depending on the version of ctags/etags, you can also do
ctags -e --recurse
to generate emacs (xemacs here) tags. You're right, they are great. In
xemacs you can also use a tags hierarchy. Say for example you have a
large source code tree, and you have a few files you work on locally.
You can list the local file's tag file first, then the large source tree
tag file and xemacs will search them in order, so it uses your
modifications first. Then it 'falls through' to the primary source
tree.
(The command is setq tab-table-alist ... Thanks Frank!)
