Usage: py-compile [--help] [--version] [--basedir DIR] [--destdir DIR] FILES..."
67
 
68
Byte compile some python scripts FILES.  Use --destdir to specify any
69
leading directory path to the FILES that you don't want to include in the
70
byte compiled file.  Specify --basedir for any additional path information you
71
do want to be shown in the byte compiled file.
72
 
73
Example:
74
  py-compile --destdir /tmp/pkg-root --basedir /usr/share/test test.py test2.py
