# (c) Canonical Ltd, 2006
# written by Alexander Belchenko for bzr project
#
# This script will be executed after installation of bzrlib package
# and before installer exits.
# All printed data will appear on the last screen of installation
# procedure.
# The main goal of this script is to create special batch file
# launcher for bzr. Typical content of this batch file is:
#  @python bzr %*
#
# This file works only on Windows 2000/XP. For win98 there is
# should be "%1 %2 %3 %4 %5 %6 %7 %8 %9" instead of "%*".
# Or even more complex thing.
#
# [bialix]: bzr de-facto does not support win98.
#           Although it seems to work on. Sometimes.
# 2006/07/30    added minimal support of win98.
# 2007/01/30    added *real* support of win98.
