"""Freeze a Python script into a binary.
|
|
|
|
usage: freeze [options...] script.py [module]...
|
|
|
|
Options:
|
|
|
|
-p prefix: This is the prefix used when you ran ``make install''
|
|
in the Python build directory.
|
|
(If you never ran this, freeze won't work.)
|
|
The default is whatever sys.prefix evaluates to.
|
|
It can also be the top directory of the Python source
|
|
tree; then -P must point to the build tree.
|
|
|
|
-P exec_prefix: Like -p but this is the 'exec_prefix', used to
|
|
install objects etc. The default is whatever sys.exec_prefix
|
|
evaluates to, or the -p argument if given.
|
|
If -p points to the Python source tree, -P must point
|
|
to the build tree, if different.
|
|
|
|
-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.
|
|
|
|
-o dir: Directory where the output files are created; default '.'.
|
|
|
|
-h: Print this help message.
|
|
|
|
-w: Toggle Windows (NT or 95) behavior.
|
|
(For debugging only -- on a win32 platform, win32 behaviour
|
|
is automatic.)
|
|
|
|
-s subsystem: Specify the subsystem; 'windows' or 'console' (default).
|
|
(For Windows only.)
|
|
|
|
Arguments:
|
|
|
|
script.py: 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 ("make install").
|
|
|
|
The script should not use modules provided only as shared libraries;
|
|
if it does, the resulting binary is not self-contained.
