File Tools/freeze/nfreeze.py

-#! /usr/local/bin/python
-
-# WARNING: this is an unsupported variant of freeze.py -- see README
-
-# "Freeze" a Python script into a binary.
-# Usage: see variable usage_msg below (before the imports!)
-
-# This version builds the frozen binary in a temporary directory;
-# courtesy Jaap Vermeulen.  Use the -l option to get the functionality
-# of the standard version.
-
-# HINTS:
-# - Edit the lines marked XXX below to localize.
-# - You must have done "make inclinstall libainstall" in the Python
-#   build directory.
-# - The script should not use dynamically loaded modules
-#   (*.so on most systems).
-
-
-# Usage message
-
-usage_msg = """
-usage: freeze [-p prefix] [-e extension] [-l] ... script [module] ...
-
--p prefix:    This is the prefix used when you ran
-              'Make inclinstall libainstall' in the Python build directory.
-              (If you never ran this, freeze won't work.)
-              The default is /usr/local.
-
--e extension: A directory containing additional .o files that
-              may be used to resolve modules.  This directory
-              should also have a Setup file describing the .o files.
-              More than one -e option may be given.
-
--l:           Local compilation. Instead of using a temporary directory
-              that is removed after succesful compilation, the current
-              directory is used and temporary files are not removed.
-
-script:       The Python script to be executed by the resulting binary.
-
-module ...:   Additional Python modules (referenced by pathname)
-              that will be included in the resulting binary.  These
-              may be .py or .pyc files.
