# (re)generate ICU data out of CLDR
#
# to use this file:
#
## 0. have ICU installed and built normally (sorry, no out-of-source - yet.)
##
## 1. make sure LDML2ICUConverter is in your path (see elsewhere)
## 
## 2. Add a file 'reslocal.mk' in icu/source/data/locales to include this file:
##      include ../../../locale/tools/scripts/cldrres.mk
##
## 3. from icu/source/data  type:  'make cldr-clean-old' to get rid of the non-CLDR files
## now just type 'make' and you should be set.
##

## Root of the CLDR directory (contains common, icu, ...)
CLDR_ROOT=../../../cldr
ICU_XML=$(srcdir)/xml

## Arguments to the LDML2ICUConverter program

## if you want draft locales - uncomment this (or, put it in reslocal.mk)
#LDML_CONVERTER_OPTS+=-f

## if you want verbose output - uncomment this (or, put it in reslocal.mk)
#LDML_CONVERTER_OPTS+=-v

## the tool. No $(INVOKE) needed.
LDML_CONVERTER=LDML2ICUConverter

## command line options to the ldml conversion tool. Shouldn't need to edit from here on down.
