/brz/remove-bazaar

# (c) Canonical Ltd, 2006

# written by Alexander Belchenko for brz project

#

# This script will be executed after installation of breezy 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 brz. Typical content of this batch file is:

#  @python brz %*

#

# 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]: brz 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.
