+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

+       perl ./mktables
+       p4 revert -a
+       cd ../..
+       perl Porting/manicheck
+
+You need to update version by hand
+
+       p4 edit version
+       ...
+       
+If any new (or deleted, unlikely but not impossible) *.pl files are indicated:
+
+       cd lib/unicore
+       p4 add ...
+       p4 delete ...
+       cd ../...
+       p4 edit MANIFEST
