Subject: [PATCH] Update the py-compile script (works with Python 3.12)
The version of automake's py-compile that lvm2 carries around in
autoconf/ is ancient. Particularly, it assumes the 'imp' module
exists, which as of Python 3.12 is no longer a safe assumption.
This just updates lvm2's copy of the file to the latest version
in upstream automake -
https://raw.githubusercontent.com/autotools-mirror/automake/4bd4640e03670e267d9763d377f107c09b4f2202/lib/py-compile
. From a quick look at the changes, the interface shouldn't have
changed, this should just work better with modern Python.

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.

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