# 	INSTALL-HDFEOS
#
# description:
# 	This script handles the installation of HDFEOS.
#
# usage:
# 	1) Set directory to HDFEOS top level directory.
# 	2) Type:
# 
# 	       bin/INSTALL-HDFEOS [-dbug] [-sgi32 | -sgi64] [-i<incdir>] [-l<libdir>] [-szi<SZincdir>] [-szl<SZlibdir>]
#              bin/INSTALL-HDFEOS [-cc_path <path/compiler_name>]
# 	       bin/INSTALL-HDFEOS [-h]
# 
# 	   Where (optional) flags are:
#
# 	      -dbug    : build debug version of HDF-EOS
# 	      -sgi32   : build in -n32 mode (SGI Power Challenge only)
# 	      -sgi64   : build in -64  mode (SGI Power Challenge only)
#             -cc_path : set the path of the C compiler to <path/compiler_name>
# 	      -i       : set HDF include directory to <libdir>
# 	      -l       : set HDF library directory to <libdir>
# 	      -h       : display this help message and exit
# 	      -szi     : set SZIP include directory to <libdir>
# 	      -szl     : set SZIP library directory to <libdir>
#
#
# 	3) Enter requested information when prompted.
# 
# notes:
# 	1) This script is compatible with the following platforms:
# 	   Sun, SGI, HP-9000, IBM RS-6000 and DEC Alpha.
# 	   It automatically figures out which platform you are on,
# 	   and sets environment variables accordingly.
