#  Name   : initial setup script for HOOPLE                                   #
#  Author : Chris Koeritz                                                     #
#                                                                             #
#  Purpose:                                                                   #
#                                                                             #
#    This script can bootstrap the HOOPLE libraries from a state where none   #
#  of the required binaries are built yet.  It will build makedep and         #
#  version_stamper and plunk them into the bin directory.  Then it will build #
#  the whole source tree (with optimization enabled) as a test of the code's  #
#  overall health.  If you want a more debuggable build, tune the build.ini   #
#  file to take out optimization and turn on debugging.                       #
#                                                                             #
