The Elixir system consists of two main software packages: Ohana (main
 developer Eugene Magnier) and Flips (main developer Jean-Charles
 Cuillandre).  The Elixir system combines these two packages, along
 with other external software products, into a complete system
 providing many utilities and functions for image processing at CFHT
 and elsewhere.  This document describes how to install the Ohana
 portion of the Elixir system.  Ohana may be installed from CVS or from
 a distributed tar ball.  Within the Elixir development community, the
 Ohana source tree may be checked out of the Elixir CVS tree.  Ohana is
 also distributed as a tar ball to users outside of the Elixir
 development community.
 
 1) Installing Ohana from source tar ball:
 
   un-gzip and untar:  
 
     > gunzip -c ohana.tgz | tar xvf -
 
   enter the ohana top-level directory:
 
     > cd ohana
 
   construct the input Configure file [1]:
 
     > configure
 
   this step will note the binary installation path.  This should be
   added to your PATH
 
   compile the software
 
     > make
 
   install the software
 
     > make install
 
 2) Installing Ohana from CVS (Developer's version):
 
   check out the ohana source tree:
 
     > setenv CVSROOT poma:/data/elixir2/srcdir/cvs
     > cvs co ohana
 
   enter the ohana top-level directory:
 
     > cd ohana
 
   construct the input Configure file [1]:
 
     > configure
 
   this step will note the binary installation path.  This should be
   added to your PATH
 
   compile the software
 
     > make
 
   install the software
 
     > make install
 
 ***** Notes *****
 
 [1] Ohana is configured for multiple architecture development, which
 is convenient for end users as well.  The libraries, include files,
 and programs, are all installed in directories with the architecture
 type appended: bin/linux, bin/sol, lib/linux, etc.  To take advantage
 of this multiple architecture organization when compiling, end users
 should arrange for the environment variable ARCH to be set based on
 the machine architecture, and for the PATH to depend on ARCH, rather
 than setting it to a fixed quantity.
