Usage: py-compile [--help] [--version] [--basedir DIR] [--destdir DIR] 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.

Example:
  py-compile --destdir /tmp/pkg-root --basedir /usr/share/test test.py test2.py

Report bugs to <bug-automake@gnu.org>.
