# Purpose:
#    To build the mozilla self-extracting installer and its corresponding .xpi files
#    given a mozilla build on a local system.
#
# Requirements:
# 1. perl needs to be installed correctly on the build system because cwd.pm is used.
# 2. mozilla\xpinstall\wizard\windows needs to be built.
#    a. to build it, MFC must be installed with VC
#    b. set MOZ_MFC=1 in the build environment
#    c. run nmake -f makefile.win from the above directory
#
