USAGE="""Usage: run.py [--install] CMD [ARG...]
Option:
--run_in_install: find extension module under lib of installation directory
Locate a Python extension module in some directory D under the
c_extensions/build subdirectory of the directory that contains the present
command. With --run_in_install, assume that this script resides in an installed
version; this means that the directory structure is different and D is located
as ../../lib.
Then run CMD [ARG...] with environment variable PYTHONPATH augmented with D.
Normally, print out a message where the extension module is found. But, with
--run_in_install this message is suppressed.
Examples:
From anywhere:
# Start include server.
/home/distcc/include_server/run.py include_server.py
In the include_server directory:
# Run include_server tests.
./run.py include_server_test.py
# Pycheck include_server.
./run.py `which pychecker` include_server.py
In installed distcc-pump:
# See 'distcc-pump' script.
$include_server_location/run.py --run_in_install include_server.py ..
