Prom-Wl is a procmail reader for Wanderlust on GNU Emacs.
If you want to install quickly, you shoud do following steps:

(1) add dot.emacs to your ~/.emacs file and change it suitable for your site
  % cat /usr/local/share/examples/prom-wl/dot.emacs >> ~/.emacs
  % vi ~/.emacs
(2) copy dot.procmailrc to ~/.procmailrc and change it suitable for your site
  % cp /usr/local/share/examples/prom-wl/dot.promailrc ~/.promailrc
  % vi ~/.promailrc
(3) byte-compile with "byte-comile" script if you want with xemacs-mule code
  # cd /usr/local/share/emacs/site-lisp
  # /usr/local/share/doc/prom-wl/byte-compile -l wl xemacs-mule prom-wl

Where detail specification for .emacs and .procmailrc may be shown in
/usr/local/share/doc/prom-wl/prom-usage.jis or procmail(1). And for
usage of byte_compile scripts, run byte-compile with -h option.
Run with "M-x prom-wl" in your emacs editors, Wanderlust will be invoked and
then search unread mails from procmail log to show unread message from top of
entries that you specfied in ~/.pronmailrc.
