 =head1 DESCRIPTION
 
-Parses the official RFC-1345 document, searching the
-'character mnemonic table' for all digraph definitions.
-If successful, Perl code is output resulting in a hash
-with character data keyed by digraph.
-Any errors and warnings are given at STDERR.
+Combines precompiled digraph includes of rfc (1345), vim, and shiar
+and outputs a complete map including character details and usage classes.
 
 The value can either be a scalar string containing another
 digraph which can be considered identical (usually inverted),
