##
## 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
