cvs-mode-tag). It's usually preferable to tag a
directory at a time. Rather than selecting all files (which too
often doesn't select all files but only the few that are
displayed), clear the selection with M-DEL
(cvs-mode-unmark-all-files), position the cursor
on the directory you want to tag and hit t.By default, ‘tag’ commands ignore the marks. This
can be changed with cvs-invert-ignore-marks. Also,
by default ‘tag’ can only be applied to
directories, see cvs-force-dir-tag if you want to
change this behavior.
