Downloading, Installing and Testing:

1. Download rgo-19jan2001.tar.gz
   This gzip-ed tar file contains the source and the precompiled Solaris/SunOS executable (ssun)
2. unpack it in a directory of your choice
   for GNU tar: gtar -zxf rgo.tar.gz
   for other tar's: gzip -cd rgo.tar.gz | tar -xf -
3. add the package definition
   

       In your loginuser.cl file make the following definitions
       somewhere before the "keep" statement.
   
           reset rgo = /Your/path/to/rgo/
           task  rgo.pkg = rgo$rgo.cl
           printf ("reset helpdb=%s,rgo$lib/helpdb.mip\nkeep\n",
               envget("helpdb")) | cl
           flpr
        

4. you should now be able to access the rgo package. Log into IRAF and load the package to test it:
   > cl
   cl> rgo
5. documentation is in rgo/doc and help should be available within IRAF for the tasks.
