# Before running this script, complete this checklist:
# * Download a copy of current GIT.
# * Download a copy of current GIT documentation files.
# * Patch the source code/package with any relevant materials.
# * Set the makefile to strip symbols.
# * Compile new 32/64 bit binaries and put them in their appropriate ./bin_unix locations.
#   (this isn't done automatically, as I compile the 32-bit binary on a virtual machine).
# * Delete all non-repository files/folders except any shadows.dat and the new binaries.

# ** CHANGE THE BELOW 4 VARIABLES BEFORE EXECUTING THE SCRIPT ** #

# Please ensure this path is NOT inside your "PATHTOACDIR" folder, as
# this will be the place the tarball package gets saved.
