The defaults for the ways in which mhn displays and stores multi-media e-mail messages can be found in the file mhn_defaults, located in the MH library directory. To find out which directory is the MH library directory, you can type this command:
% mhparam mhlprocThis prints out the path of the mhl program. In MH 6.8, mhl is in the MH library directory. The mhn_defaults file is in the same directory.
For your perusal, here are some example mhn_defaults files in use at UC Irvine's ICS Department and at Irvine Compiler Corp.
Any of the lines in these files can be picked up and modified for inclusion in your .mh_profile, or in your mhn profile named by the environment variable $MHN.
The various ``%'' escape codes used in these profiles are described
in section .
