7# This script takes libcmt.lib for VS2005/08/10/12/13 and removes the allocation
8# related functions from it.
9#
10# Usage: prep_libc.py <VCLibDir> <OutputDir> <arch>
11#
12# VCLibDir is the path where VC is installed, something like:
13#    C:\Program Files\Microsoft Visual Studio 8\VC\lib
14# OutputDir is the directory where the modified libcmt file should be stored.
15# arch is either 'ia32' or 'x64'
