-;;; Installation
-
-;; Basic
-;(autoload 'mspools-show "mspools" "Show outstanding mail spools." t)
-; Point to directory where spool files and folders are:
-; (setq mspools-folder-directory "~/MAIL/")
-;
-; If you use VM, mspools-folder-directory will default to vm-folder-directory
-; unless you have already given it a value.
-
-;; Extras
-; possibly bind it to a key:
-;(global-set-key '[S-f1] 'mspools-show)
-;(setq mspools-update t)
-
-;; Interface with the mail filter
-; We assume that the mail filter drops new mail into the spool
-; `folder.spool'. If your spool files are something like folder.xyz
-; for inbox `folder', then do
-; (setq spool-suffix "xyz")
-; If you use other conventions for your spool files, this code will
-; need rewriting.

;;; TODO
;; What if users have mail spools in more than one directory? Extend
-;; mspools-folder-directory to be a list of files?
+;; mspools-folder-directory to be a list of directories? Currently,
+;; if mail spools are in other directories, the way to read them is to
+;; put a symbolic link to the spool into the mspools-folder-directory.
;; I was going to add mouse support so that you could click on a line
;; to visit the buffer. Tell me if you want it, and I can put the
-;; code in (I dont use the mouse much, so I havent bothered with it so
-;; far).
-
+;; code in (I don't use the mouse much, so I haven't bothered with it
+;; so far).
;; Rather than showing size in bytes, could we see the number of msgs
;; waiting? (Could be more time demanding / system dependent).
-;; Perl script counts the number of /^From / occurences.
-;; ?
-;; Include date
-;; (substring (current-time-string (nth 4 (file-attributes "~/INBOX"))) 4 19)
;; Maybe just call a perl script to do all the hard work, and
;; visualise the results in the buffer.
;; Shrink wrap the buffer to remove excess white-space?
