+* uchar.h & uscript.h & uprops.h & uprops.c & genprops
+- new block & script values
+ + script values already added in ICU 3.6 because all of ISO 15924 is now covered
+
+* build Unicode data source code for hardcoding core data
+C:\cvs\oss\icu\source\data>NMAKE /f makedata.mak ICUMAKE=\cvs\oss\icu\source\data\ CFG=debug uni-core-data
+
+ICU data make path is \cvs\oss\icu\source\data\
+ICU root path is \cvs\oss\icu
+Information: cannot find "ucmlocal.mk". Not building user-additional converter files.
+[etc.]
+Creating data file for Unicode Character Properties
+Creating data file for Unicode Case Mapping Properties
+Creating data file for Unicode BiDi/Shaping Properties
+Creating data file for Unicode Normalization
+Unicode .icu files built to "\cvs\oss\icu\source\data\out\build\icudt35l"
+Unicode .c source files built to "\cvs\oss\icu\source\data\out\tmp"
+
+- copy the .c source files to C:\cvs\oss\icu\source\common
+ and rebuild the common library
+
+*** Unicode version numbers
+- makedata.mak
+- uchar.h
+- configure.in
+
+*** LayoutEngine script information
+* Run ICU4J com.ibm.icu.dev.tool.layout.ScriptNameBuilder. This generates LEScripts.h, LELanguage.h,
+ScriptAndLanguageTags.h and ScriptAndLanguageTags.cpp in the working directory. (it also generates
+ScriptRunData.cpp, which is no longer needed.)
+
+The generated files have a current copyright date and "@draft" statement.
+
+* copy the above files into <icu>/source/layout, replacing the old files.
+
+Add new default entries to the indicClassTables array in <icu>/source/layout/IndicClassTables.cpp
+and the complexTable array in <icu>/source/layoutex/ParagraphLayout.cpp. (This step should be automated...)
+
+* rebuild the layout and layoutex libraries.
