+# Usage: prep_libc.py <VCLibDir> <OutputDir> <arch> [<environment_file>]
+#
+# 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.
+#
+# If the environment_file argument is set, the environment variables in the
+# given file will be used to execute the VC tools. This file is in the same
+# format as the environment block passed to CreateProcess.
