SYNOPSIS
pycentral [-h] [-v] <cmd> [<cmd options>] [<args>]
DESCRIPTION
pycentral
provides support for installing python modules independent
of the current installed Python version and handling
byte-compilation and -removal tasks in installation scripts.
OPTIONS -v, --version
Limit the output to the version numbers of the python versions.
-h, --help
Print a help text.
pycentral has the following sub commands. For fine grained help, call: pycentral <cmd>.
bccompile
Byte compile .py files in a package.
bcremove
Remove the byte compiled .py files.
list List all managed files.
pkginstall
Make a package available for all supported runtimes.
pkgprepare
Prepare a package for all supported runtimes.
pkgremove

showversions

version

FILES
/etc/python/debian_config is searched for the attribute overwrite-local. If set to 1, or True, existing files in
/usr/lib/pythonX.Y/*-packages are overwritten with symbolic links to the pycentral install area. The default is to abort the installation
of a package, when files already exist. This behaviour may be useful, when python libraries were manually installed into this directory.
The attribute byte-compile can be set to a comma separated list of the values standard and optimze to indicate how files should be byte-
compiled.
