+# "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.
