 # - Edit the lines marked XXX below to localize.

 # - You must have done "make inclinstall libainstall" in the Python
 #   build directory.
+# - The script name should end in ".py".
 # - The script should not use dynamically loaded modules

 # Usage message
 
 usage_msg = """
-usage: freeze [-p prefix] [-e extension] ... script [module] ...
+usage: freeze [-p prefix] [-P exec_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.
 
+-P exec_prefix: Like -p but this is the 'exec_prefix', used to
+		install objects etc.  The default is the value for -p.
+
 -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.
+	      It *must* end with a .py suffix!
 
 module ...:   Additional Python modules (referenced by pathname)
               that will be included in the resulting binary.  These
               may be .py or .pyc files.
+
+NOTES:
+
+In order to use freeze successfully, you must have built Python and
+installed it.  In particular, the following two non-standard make
+targets must have been executed:
+
+	make inclinstall
+	make libainstall		# Note: 'liba', not 'lib'
+
+The -p and -P options passed into the freeze script must correspond to
+the --prefix and --exec-prefix options passed into Python's configure
+script.
