## Makefile for rebuilding 'unsafe backward' data

## License & terms of use: http://www.unicode.org/copyright.html
## Copyright (c) 2015, International Business Machines Corporation and

##
## CONFIGURATION:
## 1. create Makefile.local containing overrides if necessary:
## BUILD_ROOT=/home/user/icu-build (location of 'config.status' etc.)
## PATH_VAR=DYLD_LIBRARY_PATH (if on OSX etc)
##
## UPDATING
## 1. make 'reset-icu' will reset ICU to 'bootstrap' state, zeroing out source/i18n/collunsafe.h
## 2. make 'gen-file' will generate and test source/i18n/collunsafe.h
subdir=tools/gencolusb

SOURCE_ROOT=$(shell cd ../.. ; pwd)
