vchoi_fork

[svn-r3329] Purpose:
    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)
