# Builds ICU a whole lotta times and with different options
# Set the options below and execute this script with the shell.

# This script is checked into tools/trunk/release/c. It assumes that the
# icu directory is at the same level as the tools  directory. If this
# is not the case, use the uconfigtest.local file to set the
# SRC_DIR variable to point at the ICU source directory. 
# Or, alternatively, you can make a symlink tools/icu -> your_icu_dir
# You can also use the uconfigtest.local file to override the BUILD_DIR
# and ICUPLATFORM variables.

# It can be handy to run 'tail -F uconfigtest/stats' in another window to see where things are.
