Steps for building ICU data from CLDR:

Users of CLDR:
1. Download cldrtools.zip from the CLDR website (http://www.unicode.org/cldr/repository_access.html) and unzip in a directory 
2. Download cldr.zip from the CLDR website (same as above) and unzip in cldr directory
3. Check out ICU from ICU CVS repository  http://www.ibm.com/software/globalization/icu/repository.jsp
4. Set the required environment variables
        export JAVA_HOME=<path>/java
        export ANT_OPTS="-DCLDR_DTD_CACHE=<path>/temp/cldrdtd"
        export CLDR_DIR=<path>/cldr   
        export CLDR_JAR=<path>/cldr.jar
        export ICU4C_DIR=<path>/icu
        export ICU4J_JAR=<path>/icu4j.jar 
        export UTILITIES_JAR=<path>/utilities.jar
5. Change directory to <path>/icu/source/data/
6. Enter command
   <path>/ant/bin/ant clean all
   
Developers of CLDR:
1. Check out CLDR from the CVS repository http://www.unicode.org/cldr/repository_access.html and build the tools.
2. Check out ICU from ICU CVS repository http://www.ibm.com/software/globalization/icu/repository.jsp and build it.
3. Check out ICU4J from ICU CVS repository http://www.ibm.com/software/globalization/icu/repository.jsp and build it.
4. Set the required environment variables
        export JAVA_HOME=<path>/java
        export ANT_OPTS="-DCLDR_DTD_CACHE=<path>/temp/cldrdtd"
        export CLDR_DIR=<path>/cldr   
        export CLDR_CLASSES=<path>/cldr/tools/java/classes
        export ICU4C_DIR=/work/icu
        export ICU4J_CLASSES=<path>/icu4j/classes
5. Change directory to <path>/icu/source/data/
6. Enter command
   <path>/ant/bin/ant clean all

Debugging in Eclipse:
1. From Eclipse select Run > Run from toolbar
2. Click New button
3. Go to Main tab and enter 
    Name: Ant_Launcher
    Project: cldr
    Main class: org.apache.tools.ant.launch.Launcher
4. Go to Arguments tab and enter
    Program Arguments: -buildfile c:\work\cldr\tools\java\build.xml  icu4c
    VM Arguments: -classpath C:\work\apache-ant-1.6.1\lib\ant-launcher.jar 
                  -Dant.home=C:\work\apache-ant-1.6.1 
                  -DCLDR_DTD_CACHE=/work/temp/cldrdtd/
5. Go to Environment tag and create new variables
        CLDR_DIR=<path>/cldr   
        CLDR_CLASSES=<path>/cldr/tools/java/classes
        ICU4C_DIR=/work/icu
        ICU4J_CLASSES=<path>/icu4j/classes
6. Set a break point in CLDRBuild or the tool class that needs to be debugged.
