Usage: py-compile [options] FILES...
|
|
|
|
Byte compile some python scripts FILES. Use --destdir to specify any
|
|
leading directory path to the FILES that you don't want to include in the
|
|
byte compiled file. Specify --basedir for any additional path information you
|
|
do want to be shown in the byte compiled file.
|
|
|
|
Options:
|
|
--basedir DIR Prefix all FILES with DIR, and include in error messages.
|
|
--destdir DIR Prefix all FILES with DIR before compiling.
|
|
-v, --version Display version information.
|
|
-h, --help This help screen.
|
|
|
|
Example:
|
|
py-compile --destdir /tmp/pkg-root --basedir /usr/share/test test.py test2.py
