# SYNOPSIS
#
#   AX_MPIP([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
#
# DESCRIPTION
#
#   Test for mpiP: Lightweight, Scalable MPI Profiling
#   (http://mpip.sourceforge.net/)
#
#   Provides a --with-mpiP=DIR option. Searches --with-mpiP location and the
#   usual places for mpiP and required libraries.  Marks MPIP as a precious
#   environment variable.
#
#   On success, sets MPIP_LDFLAGS, MPIP_LIBS, #defines HAVE_MPIP, and calls
#   ACTION-IF-FOUND. When ACTION-IF-NOT-FOUND is not specified, the default
#   behavior is for configure to fail.
