# This script takes libcmt.lib for VS2005/08/10/12/13 and removes the allocation
# related functions from it.
#
# Usage: prep_libc.py <VCLibDir> <OutputDir> <arch>
#
# VCLibDir is the path where VC is installed, something like:
# C:\Program Files\Microsoft Visual Studio 8\VC\lib
# OutputDir is the directory where the modified libcmt file should be stored.
# arch is one of: 'ia32', 'x86' or 'x64'. ia32 and x86 are synonyms.
