%description
The NVIDIA PMDA is a PCP module for gathering metrics on the performance of 
NVIDIA graphics cards.

By default, this package will install the PMDA as both a collector and monitor,
and it will run in DSO mode. To use the PMDA in a different configuration,
re-run the install script in its folder. It will also first add this PMDA to
the PCP namespace file, if it has not already been included.

This spec file is partially based on the pcp-pmda-infiniband RPM.
