+description = """Process Management for Exascale Environments
+PMI Exascale (PMIx) represents an attempt to
+provide an extended version of the PMI standard specifically designed
+to support clusters up to and including exascale sizes. The overall
+objective of the project is not to branch the existing pseudo-standard
+definitions - in fact, PMIx fully supports both of the existing PMI-1
+and PMI-2 APIs - but rather to (a) augment and extend those APIs to
+eliminate some current restrictions that impact scalability, and (b)
+provide a reference implementation of the PMI-server that demonstrates
+the desired level of scalability.
