 The two big files, NormalizationTest.txt (2.0MB) and Unihan.txt
 (25.7MB) were not included due to space considerations.  Also NOT
-included were any *.html files and the derived files:

+    DerivedAge.txt
+    DerivedCoreProperties.txt
+    DerivedNormalizationProps.txt
+
+To be 8.3-friendly, the lib/unicore/PropertyValueAliases.txt was
+renamed to be lib/unicore/PropValueAliases.txt, since otherwise

+FOR PUMPKINS
+
+The *.pl files are generated from the *.txt files by the mktables script:
+       
+       cd lib/unicore
+       cp .../UnicodeOriginal/*.txt .
+       rm NormalizationTest.txt Unihan.txt Derived*.txt
+       p4 edit Properties *.pl */*.pl
+       perl ./mktables
+       p4 revert -a
+       cd ../..
+       perl Porting/manicheck
+
+You need to update version by hand
 
-       DerivedAge.txt
-       DerivedCoreProperties.txt
-       DerivedNormalizationProps.txt
-       DerivedProperties.txt
+       p4 edit version
+       ...
+       
+If any new (or deleted, unlikely but not impossible) *.pl files are indicated:
 
-and the normalization-related files
+       cd lib/unicore
+       p4 add ...
+       p4 delete ...
+       cd ../...
+       p4 edit MANIFEST
+       ...
 
-       NormalizationCorrections.txt
