# The way this thing works:
#
# + A packages file is parsed.  This file contains something 
#   that looks like this (note that spaces are illegal):
#
#   +----------------------------------------------
#   |nspr:nsprpub
#   |core:build,db,xpcom,intl,js,modules/libutil,modules/security/freenav,modules/libpref,modules/libimg,modules/libjar,caps
#   |network:netwerk
#   |layout:htmlparser,gfx,dom,view,widget/timer,widget,layout,webshell,editor,modules/plugin
#   |xpinstall:xpinstall
#   |profile:profile
#   |xptoolkit:xpfe,rdf
#   |cookie:extensions/cookie
#   |wallet:extensions/wallet
#   |mailnews:mailnews
#   +----------------------------------------------
#
# + For each package, a list of modules corresponding to that
#   package is parsed.  Each modules corresponds to a 
#   directory somewhere in a mozilla build tree - usually
#   the toplevel ones (ie, layout, nsprpub, xpcom) but not
#   always (ie, extensions/wallet)
#
# + For each module, print-module-filelist.sh is invoked.
#   The output of that is parsed and converted from the 
#   crazy mozilla install hierarchy to something that
#   makes sense on a linux box.
#
#   For example:  
#
#     bin/components/libraptorhtml.so
#   
#   becomes
#
#     %{prefix}/lib/mozilla/components/libraptorhtml.so
#
# + Also, this script determines which files belong in 
#   a devel package.  For example, "include/*" and "idl/*"
