Installation instructions:

Unzip this package in the directory of your choice (I would suggest
/usr/local/ifile/) and then run the install script (if you do not have perl
installed in /usr/bin, you will need to edit 'install.perl' and change the
first line to the proper directory).

The script will search for certain binaries, prompting you if it cannot find
them.  If you are prompted and aren't sure of their location, stop the
installation (Ctrl-C) and take the time to find them.

Once it has the directory information, the installation program will backup
the current mh refile program and replace it with a link to irefile.  It will
also add two lines to your .maildelivery file (creating it if necessary) 
which will have slocal run the ifilter program.

Finally, once the script has finished, you must change the
"Incorporate Mail -> Ways to Inc" option within EXMH to "presort".

With the install program run, ifile is ready to be used by your user account.
The only effect this installation will have on other users of your system is
that now all users will use the irefile script instead of the standard MH
refile script.  In the context of EXMH, the only difference should be a
noticable slowdown in refiling operations.

To allow other users to use the ifile filtering system, each user must
change their Inc option to presort and must add the following line to their
.maildelivery file:

* - ^ ? /ifile/install/directory/ifilter
