WARNING!!

These directories contain some Unicode tools used to build various files,
and to check the consistency of the Unicode releases.

- They are NOT production level code, and should never be used in programs.
- The API is subject to change without notice, and will not be maintained.
- The source is uncommented, and not well structured -- classic spaghetti style.
- There is no build mechanism.
- I have not checked to make sure it works on Unix; probably the only change that
  needs to be made is to fix the file separator.

Instructions:

1. You must edit UCD_Types at the top, to set the directories for the build:

    public static final String DATA_DIR = "C:\\DATA\\";
    public static final String UCD_DIR = BASE_DIR + "UCD\\";
    public static final String BIN_DIR = DATA_DIR + "BIN\\";
    public static final String GEN_DIR = DATA_DIR + "GEN\\";

Make sure that each of these directories exist. Also make sure that the following
exist:

<GEN_DIR>/DerivedData
<GEN_DIR>/DerivedData/ExtractedProperties
<UCD_DIR>/EXTRAS-Update


2. Download all of the UnicodeData files for each version into UCD_DIR.
The folder names must be of the form: "3.2.0-Update", so rename the folders on the Unicode site to this format.


2a. If you are downloading any "incomplete" release (one that does not contain
a complete set of data files for that release, you need to also download the previous
complete release). All of the N.M-Update directorys are complete, *except* for 4.0-Update,
which does not contain a copy of Unihan.txt.


2b. If you are building any of the UCA tools, you need to get a copy of the UCA data file
from http://www.unicode.org/reports/tr10/#AllKeys. The default location for this is:

        BASE_DIR + "Collation\\allkeys" + VERSION + ".txt".
        
If you have it in a different location, change that value for KEYS in UCA.java, and 
the value for BASE_DIR


2c. Here is an example of the default directory structure with files:

C://DATA/

        BIN/
    
        Collation/
            allkeys-3.1.1.txt
        
        GEN/
            DerivedData/
                ExtractedProperties
        UCD/
            3.0.0-Update/
                Unihan-3.2.0.txt
                ...
            4.0.0-Update/
                ArabicShaping-4.0.0d14b.txt
                BidiMirroring-4.0.0d1b.txt
                ...
            EXTRAS-Update/


3. All of the following have "version X" on the command line. If you want a specific version
like 3.1.0, then you would write "version 3.1.1". If you want the latest version (4.0.0),
you can omit the "version X".

3. For each version, the tools build a set of binary data in BIN that contain
the information for that release. This is done automatically, or you can manually do it
with:

  java <UCD>Main version X build

This builds an compressed format of all the UCD data (except blocks and Unihan)
into the BIN directory. Don't worry about the voluminous console messages, unless one says
"FAIL".


4. To build all of the Unicode files for a particular version X, run

  java <UCD>Main version X all
  

4a. To build a particular file, like CaseFolding, use that file name instead of all

  java <UCD>Main version X CaseFolding
  

4b. All of the generated files get a "d" version number, e.g. CaseFolding-4.0.0d3.txt.
To change the D version on generated files, edit the link in GenerateData.java:

    static final int dVersion = 2; // change to fix the generated file D version. If less than zero, no "d"


5. To run basic consistency checking, run:

  java <UCD>Main version X verify

Don't worry about any console messages except those that say FAIL.


6. To build all the UCA files used by ICU, use the option:

    java <UCA>Main ICU
