Instructions for use on a CIT astronomy cluster machine:

For machines connected to the Caltech astronomy cluster, you can run the 
latest release version of the lpipe LRIS reduction pipeline without 
having to actually install any software.  

----- Single-session use:

For one-time use, simply execute the following command before starting IDL:

   source /home/dperley/progs/idl/lpipe/citsetup.src

(You may first need to "unsetenv IDL_STARTUP" and/or "unsetenv IDL_PATH" if you have
 an existing, competing installation.)


----- Multi-session use for non-IDL users:

If you don't already have an .idlenv file in your home directory, then add the
following line to your .cshrc file:

   source ~/.idlenv

Then create the file .idlenv in your home directory and add the following line:
   
   setenv IDL_PATH /usr/local/harris/idl88/lib:+/home/dperley/progs/idl/lpipe:+/home/dperley/progs/idl/lpipe/dependencies:+/home/dperley/progs/idl/gsfc/pro


----- Multi-session use for IDL users:

If a .idlenv file already exists in your home directory, open it and add the 
following string to your IDL_PATH keyword:

  :+/home/dperley/progs/idl/lpipe:+/home/dperley/progs/idl/lpipe/dependencies

If you don't already have the GSFC IDLastro package installed, also add:

  :+/home/dperley/progs/idl/gsfc/pro
