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