will set up your HOPS environment by modifying the following variables:

    PATH            executable search path
    INFOPATH        info file search path
    LD_LIBRARY_PATH adds dynamic linkage to PGPLOT_DIR
    PYTHONPATH      for a few useful python tools

    HOPS_ROOT       root of the HOPS package
    HOPS_VERS       version number of this package
    HOPS_ARCH       installation architecture
    HOPS_DOCS       program documentation support
    HOPS_SETUP      is set true after invocation
    HOPS_QUIET      controls setup diagnostics
    HOPS_PREFIX     directory where hops was installed

    PGPLOT_DIR      sets this appropriately if not otherwise defined
    PGPLOT_TYPE     sets this to /xw if not defined
    PGPLOT_DEV      sets this to /xw if not defined
    PROGDOC         used by HOPS vhelp to find help texts
    TEXT            used by HOPS for text configuration files
    AHELP           used by aedit for help texts
    DEF_CONTROL     used by fourfit
    GS_DEVICE       used by ghostscript
    DATADIR         parent of experiment data directory
    TESTDATADIR     directory for hops test data

    SCHEDDIR, AFILEDIR, SYSVEX, TASK, BIN, TMP
		    heritage variables that are
		    assigned but perhaps not used

    MK4_PRINTER	    can be pointed to your preferred printer

Set HOPS_QUIET (to anything) if you do not want the chatter.
Once setup, HOPS_SETUP is defined to be "true".  You can set this
to "false" to reinitialize with a different version of the software,
e.g. something like one of these (depending on which '$zero')

    HOPS_SETUP=false . ~/bin/'$zero'
    HOPS_SETUP=false . @prefix@/'$zero'

Otherwise, reinvocation will merely tell you what you are using.
To purge HOPS from your environment, set HOPS_SETUP to "purge".
