New feture
Description:
# Try to locate the HDF (nicknamed hdf4) software
# This is a hack because there is no consistent place to find
# the valid HDF library.
# Usage: locate_hdf5
# It prints two strings in which the first one represents a valid
# value for the --with-hdf=... switch and the second one is where
# one can find the hdp command. It can be added to the $PATH.
Platforms tested:
Pecos (solaris 5.7)
