+# Generate utt tables.
+
+# The source file pcre_tables.c contains (amongst other things), a table that
+# is indexed by script name. In order to reduce the number of relocations when
+# loading the library, the names are held as a single large string, with 
+# offsets in the table. This is tedious to maintain by hand. Therefore, this
+# script is used to generate the table. The output is sent to stdout.
