 CLDR Tools ReadMe
 -----------------
 
-The tools folder will contain tools, tests, and utilities for dealing with CLDR data.
-The code is very preliminary, so don't expect stability from the APIs (or documentation!),
-since we still have to work out how we want to do the architecture.
+This directory contains tools, tests, and utilities for dealing with CLDR data.
 
-See: http://cldr.unicode.org/development/new-cldr-developers
-
-The directory structure is:
-[./org/unicode/cldr..]
-icu  	Tools for generating ICU-format data from CLDR
-posix	Tools for generating POSIX-format data from CLDR
-test	Test tools for CLDR
-json    Tools for creating JSON data from CLDR
-tool	Tools for manipulating CLDR files
-util	Utilities for handling CLDR files
-ooo 	OpenOffice.org tools for :
-			- Converting OpenOffice.org format to LDML
-			- CLDR data to OpenOffice.org format
-			- Comparing OpenOffice.org data
------------------
-
-The tools may use ICU4J code for testing, but should use none of the data in ICU4J.
-We'll be using the ICU4J test framework also (we looked at JUnit, but it would be
-really clumsy for the ways in which we'd have to test).
-
-
-TO BUILD AND RUN THE TOOLS:
-
-  See http://cldr.unicode.org/tools
-
-ADVANCED USAGE:
-
-1.  Build the tools with the following command:
-
-   ant clean all jar
-
-2. For a list of build targets use the following command:
-
-   ant -projecthelp
-
-3. For running automated and console tests, you will want to create a 'build.properties' file.
-
-    If you checked out CLDR as one directory (i.e. there is a ../../common relative to this readme),
-    then create build.properties containing:
-
-              CLDR_DIR=../..
-
-    Otherwise, if inside of an eclipse workspace (i.e. there is a ../common relative to this readme),
-    this may work for you:
-
-              CLDR_DIR=..
-
-CLDR TOOL DEVELOPMENT ON ECLIPSE IDE
