##
## This script is meant to run a mozilla program from the mozilla
## source tree. This is mostly useful to folks hacking on mozilla.
##
## A mozilla program is currently either viewer or mozilla-bin. The
## default is viewer.
##
## The script will setup all the environment voodoo needed to make
## mozilla work.
#
##
## Standard shell script disclaimer blurb thing:
##
## This script is a hack. It's brute force. It's horrible.
## It doesn't use Artificial Intelligence. It doesn't use Virtual Reality.
## It's not perl. It's not python. It probably won't work unchanged on
## the "other" thousands of unices. But it worksforme. --ramiro
##
## If you have an improvement, patch, idea, whatever, on how to make this
## script better, post it here:
##
## news://news.mozilla.org/netscape.public.mozilla.patches
## news://news.mozilla.org/netscape.public.mozilla.unix
##
#
##
## Potential improvements:
##
## + Run from anywhere in the tree.
## + Run ldd on the program and report missing dlls
## + Deal with NSPR in the tree
## + All the other unices
