# This script must be run as root
#
# If icmake and the bobcat library haven't yet been installed on your system 
# execute the folllowing steps to install them.
# Once the following steps have been executed they don't need to be executed
# again as from that point onward icmake and the bobcat library are available
# on your system, and new versions can be constructed using the available 
# icmake and bobcat versions.
#   
#   1. extract the bobcat tar to its construction directory
#   2. copy this file to that directory
#   3. chdir to bobcat's construction directory
#   4. call ./initialbobcatlib
#      this constructs /usr/lib/libicmake.a
#      and installs the bobcat header files in 
#      /usr/include/bobcat
#   5. chdir to icmake's construction directory
#   6. run ./icm_prepare ./icm_bootstrap, and ./icm_install as described in 
#      icmake's QUICKINSTALL
#
#   Following this, icmake is available, using its dedicated bobcat library
#   Next construct and install the bobcat (shared) library as described in
#   bobcat's INSTALL file
#   When the full library is installed, rebuild icmake so it'll use the 
#   shared bobcat library by executing, in icmake's construction directory:
#       ./build distclean
#       ./icm_prepare /
#       ./build                     (uses icmake, or use ./icm_bootstrap x)
#       ./icm_install strip all
#   as described in icmake's QUICKINSTALL file
#
# These steps only have to be performed once. Thereafter, with new versions of
# either bobcat or icmake, the then available versions of bobcat and icmake
# can be used.
