# --------  --------  ----------------------------------------------
# pforstma  26/01/96  created 
# gfilippi  30/01/96  included in DEC95
# counnas   13/06/96  GNU installation on HP-UX10.10
# gfilippi  19/06/96  included in JUN99
# gfilippi  16/09/96  NOV96
# gfilippi  14/11/96  NOV96 - added verification steps
# gfilippi  16/11/96  NOV96 - HP-UX10 and Solaris merged
# wpirani   01/04/97  Testing/hacking new installation in /vlt/local
# wpirani   09/04/97  More testing/hacking for installation in /vlt/gnu
# wpirani   03/11/97  Fine tuning for NOV97
# gfilipi   30/12/97  Fixed version of installed products
# wpirani   02/11/98  Existing /opt/gnu no longer removed on Solaris
#
# Installation of GNU products
#
# NOTES:
#
# * Now looks for the environment variable GNU_ROOT (usually /vlt/gnu/).
#   If not defined, uses /usr/local instead -- Werther Pirani
#
# PREREQUISITES:
#
# * $GNU_ROOT directory structure is created but empty:
#
# - bin
# - doc
# - etc
# - include
# - lib
# - man/man1
# - info
#
# 
# * $GNU_ROOT/bin is in $PATH
#
#
# * additional requirements for HP-UX-10:
#
#   * cc & make from HP already installed.
#     tested with 
#
#       $  what `which c89`
