## Usage:
##
## $ run-mozilla.sh [options] [program] [program arguments]
##
## This script is meant to run a mozilla program from the mozilla
## source tree.  This is mostly useful to folks hacking on mozilla.
##
## The script will setup all the environment voodoo needed to make
## mozilla work.
##
## In the absence of a program being specified on the command line, the
## script determines which program to run in this order of existence.
##
##   1. The program named foo-bin where foo is the name of this script,
##      (e.g. rename this script as TestEmbed and it will look for
##      TestEmbed-bin).
##   2. The "viewer" executable.
##   3. The "mozilla-bin" executable
#
## 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
