+
+# Given a Python script, create a binary that runs the script.
+# The binary is 100% independent of Python libraries and binaries.
+# It will not contain any Python source code -- only "compiled" Python
+# (as initialized static variables containing marshalled code objects).
+# It even does the right thing for dynamically loaded modules!
+# The module search path of the binary is set to the current directory.
+#
+# Some problems remain:
+# - You need to have the Python source tree lying around as well as
+#   the various libraries used to generate the Python binary.
+# - For scripts that use many modules it generates absurdly large
+#   files (frozen.c and config.o as well as the final binary),
+#   and is consequently rather slow.
+#
+# Caveats:
+# - The search for modules sometimes finds modules that are never
+#   actually imported since the code importing them is never executed.
+# - If an imported module isn't found, you get a warning but the
+#   process of freezing continues.  The binary will fail if it
+#   actually tries to import one of these modules.
+# - This often happens with the module 'mac', which module 'os' tries
+#   to import (to determine whether it is running on a Macintosh).
+#   You can ignore the warning about this.
+# - If the program dynamically reads or generates Python code and
+#   executes it, this code may reference built-in or library modules
+#   that aren't present in the frozen binary, and this will fail.
+# - Your program may be using external data files, e.g. compiled
+#   forms definitions (*.fd).  These aren't incorporated. By default,
+#   the sys.path in the resulting binary is only '.' (but you can override
+#   that with the -P option).
+#
+# Usage hints:
+# - If you have a bunch of scripts that you want to freeze, instead
+#   of freezing each of them separately, you might consider writing
+#   a tiny main script that looks at sys.argv[0] and then imports
+#   the corresponding module.  You can then make links to the
+#   frozen binary named after the various scripts you support.
+#   Pass the additional scripts as arguments after the main script.
+#   A minimal script to do this is the following.
+#       import sys, posixpath
+#       exec('import ' + posixpath.basename(sys.argv[0]) + '\n')
+#
+# Mods by Jack, August 94:
+# - Removed all static configuration stuff. Now, Setup and Makefile files
+#   are parsed to obtain the linking info for the libraries. You have to
+#   supply the -B option, though.
+# - Added -P (set sys.path) and -I/-D/-L/-l options (passed on to cc and
+#   ld).
