These scripts just put in the path to the compiler and debugger into the
path statement and add a couple environment variables. 

    PATH="/opt/intel/fc/9.0/bin:$PATH"; export PATH
    LD_LIBRARY_PATH="/opt/intel/fc/9.0/lib:$LD_LIBRARY_PATH"; export
LD_LIBRARY_PATH
    MANPATH="/opt/intel/fc/9.0/man:${MANPATH}"; export MANPATH

with if statements to find the status / existence of the variables.
Yes, the first thing I did was inspect the scripts to see what they did
before even thinking of running them.

After putting the path and script name into the profile.d, should I log
out and back in again for it to take effect, or?

I found the following site for checking the environment settings
http://www.comptechdoc.org/os/linux/usersguide/linux_ugenvironment.html

(didn't want to just issue commands and fubar everything :) )

Thanks for the info Paul, you, Alexander and others are great assistance
to the rest of us as we get up to speed on everything.
