 Description:
-This directory contains the source code of ICU 4.6 for C/C++
+This directory contains the source code of ICU 51.2for C/C++
 
 1. It was obtained with the following:
 
-    $ svn export --native-eol LF http://source.icu-project.org/repos/icu/icu/tags/release-4-6 icu46
+    $ svn export --native-eol LF http://source.icu-project.org/repos/icu/icu/tags/release-51-2 icu51
 
-2. Platform header files for Linux, FreeBSD, OpenBSD, Android and Mac OS X:
-
-   - Apply platform.patch in patches directory. : It applies the upstream
-     patch to platform.h.in (see http://bugs.icu-project.org/trac/ticket/8248)
-     and change source/common/unicode/ptypes.h to refer to plinux.h and
-     pmac.h generated below.
-
-   - 'runConfigureICU Linux', 'runConfigureICU FreeBSD', and
-     'runConfigureICU MacOSX' are run to generate
-     source/common/unicode/platform.h.
-
-   - On OpenBSD, source/common/unicode/platform.h is being generated
-     by the icu4c port in the ports directory and not by runConfigureICU.
-     In case the file has to be updated you can do:
-     cd /home/ports/textproc/icu4c && make configure
-
-   - Rename it to 'plinux.h', 'pfreebsd.h', 'popenbsd.h' and 'pmac.h'
-
-   - Apply patches/pmach.h.patch on Mac to pmac.h
-
-   - On Android, the pandroid.h was generated by copying plinux.h to
-     pandroid.h and applying the patches/pandroid.h.patch.
-
-   - Apply the CL at https://codereview.chromium.org/15973007/ to plinux.h
-
-3. The following directories were removed because they're not used by Chromium
-   at the moment:
-   as_is
-   packaging
-   source/extra
-   source/sample
-   source/layout
-   source/layoutex
-
-
-4. The word breaking for Chinese and Japanese were modified to use a word
-   frequency list with the following patch and cjdict.txt.
-  
-   - patches/segmentation.patch :
-       Adds a dictionary (word-frequency)-based word breaking for CJK
-       (Korean is supported in the code, but it does not do anything
-        because we don't have a Korean word-list.)
-
-   - source/data/brkitr/cjdict.txt :
-       Chinese and Japanese word frequency list.
-       See the file for license/copyright notice
-
-   - source/data/brkitr/cc_edict.txt :
-       the list of words derived from CC-Edict.)
-
-   - patches/brkitr.patch
-     * word.txt : Chinese/Japanese segmentation rules, Hebrew-script-specific
-                  handling of U+0022, and splitting of FQDN into labels at '.'.
-		  For Hebrew, see http://unicode.org/cldr/track/ticket/3120
-     * line.txt : Incorporated line_he and minor changes in CL, OP and ID
-                  definitions.
-		  For Hebrew, see http://unicode.org/cldr/track/ticket/4004
-		  For others, see http://unicode.org/cldr/track/ticket/3974
-		                  http://unicode.org/cldr/track/ticket/4200
-		                  http://unicode.org/cldr/track/ticket/
-     * brklocal.mk : build file changes to drop unnecessary brkitr rule
-                     files (e.g. word_ja.txt, line_he.txt)
-
-   - android/brkitr.patch (to be applied for Android build only) :
-       Reverts some changes about Chinese/Japanese segmentation rules in
-       patches/brkitr.patch to reduce binary size for Android.
-
-   If you want to run ICU tests, you have to copy source/data/brkitr/cjdict.txt
-   to source/test/testdata/cjdict-truncated.txt to pass TestTrieWithValue test.
-
-5. Converter changes : converters.patch
-  - Include what we really need. See source/data/mappings/ucmlocal.txt
-  - Alias and mapping changes : source/data/mappings/convrtrs.txt
-  - Changes several tables and add six new tables, three of which
-    are 'fake' tables for ISO-2022-CN(-Ext).
-  - ucnv2022.c is modified to use 3 'fake' tables added above for
-    ISO-2022-CN(-Ext).
-
-6. Locale changes
-  - patches/locale1.patch :
-      Filipino, Amharic, and Swahili locales
-      exemplar character set changes for CJK + 9 Indian locales
-      Minor fixes for Danish, , Turkish, and Korean.
-
-  - patches/locale2.patch :
-      The minimum locale data Chrome needs for 47 languages Chrome is
-      not localized to. Each locale data file has ExemplarCharacters,
-      LocaleScript, layout, and the name of the language for a locale
-      in its native language.
-
-  - patches/locale3.patch : Locale build configuration files. They
-    add reslocal.mk or {trns,sprep,rbnf,coll}local.mk files to
-    source/data/{coll,curr,lang.locale,curr,region,translit,zone,rbnf,sprep}.
-
-  - In source/data/region, run the following command to get rid of numeric region
-    display names we don't use (everything other than 419).
-     $ sed -i  '/[0-35-9][0-9][0-9]{/ d' *.txt
-
-  - android/patch_locale.sh (to be run for Android build only):
-      Makes changes to source/data/{curr,region,lang} to exclude these data
-      except the language and script names of zh_Hans and zh_Hant.
-
-7. Removal of unihan collation tables from data/coll/{zh,ja,ko}.txt
-
-  - patches/unihan.patch:
-    unihan collation tables are never used in Chrome/Webkit, but it takes
-    about 1MB in the uncompressed ICU data file in ICU 4.2.1.
-
-8. Timezone data update
-  - Grab the latest version of the following timezone data files and
-    put them in source/data/misc.
-
-     metaZones.txt
-     timezoneTypes.txt
-     windowsZones.txt
-     zoneinfo64.txt
-
-   As of Nov, 2011, the latest version is 2011n and the above files
-   are available at
-   http://source.icu-project.org/repos/icu/data/trunk/tzdata/icunew/2011n/44/
-
-9. Build-related changes
-
-  - patches/wpo.patch
-  - patches/vscomp.patch
-    (see http://bugs.icu-project.org/trac/ticket/8355 and
-         http://bugs.icu-project.org/trac/ticket/8356 )
-  - patches/rtti.patch : Make RTTI work without exception handling on Windows
-    (see http://bugs.icu-project.org/trac/ticket/8343)
-  - patches/data.build.patch :
-      To remove some data files we don't use and cut down the data size.
-  - patches/data.build.win.patch :
-      Windows-only data build patch. Add a new target DATALIB to makedata.mak
-  - patches/clang.patch: To build with Clang.
-    (see http://bugs.icu-project.org/trac/ticket/8954 Two other chunks in
-    the patch have already been fixed in the ICU trunk.)
-  - add an empty file (stubdatabuilt.txt) to source/stubdata
-
-10. Pre-built data libraries are checked in.
-
-    Before building data file on Linux, re-run runConfigureICU Linux again
-    if it's run without data.build.patch in #8 above.
-
-    'make' will fail in the 1st pass. Copy source/data/in/coll/invuca.icu
-    to {BUILD_DIR_ROOT}/data/out/build/icudt46l/coll and re-run 'make'
-    in {BUILD_DIR_ROOT}/data.
-
-    - source/data/in/icudt46l.dat : Built on Linux with all the patches
-      above applied,
-
-    - windows/icudt.dll : With icudt46l.dat in place, all the patches applied
-      and header files moved (#11 below), generated by building icudt_build
-      project of build/icudt_build.sln on Windows. icudt46.dll is
-      generated in bin/{Release,Debug} and copied to windows/icudt.dll
-      and checked in. Note that we drop the version number ('46') from the
-      dll name to avoind having to update our build scripts/configuration
-      files everytime ICU is upgraded to a new version.
-
-    - {mac,linux}/icudt46l_dat.S : Built on Mac and Linux with all the
-      patches above (except android/brkitr.patch) applied and checked in.
-
-    - android/icudt46l_dat.S : Built on Linux with all the patches above and
-      android/brkitr.patch applied and android/patch_locale.sh executed, and
-      checked in.
-
-11. The header files were moved as shown below:
-
-   source/common/unicode ==> public/common/unicode
-   source/i18n/unicode   ==> public/i18n/unicode
-
-12. Apply the fix found with static analysis tools such as PSV and coverity
-
-  - patches/static.analysis.patch
-  - upstream trunk/4.8 do not have this code any more.
-
-13. Fix for msvs2010 applied:
