- # "Freeze" a Python script into a binary.
- # Usage: see variable usage_msg below (before the imports!)
-
- # 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: freeze [-p prefix] [-e extension] ... 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.
-
- 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.
