""" Utility for parsing HTML entity definitions available from:
|
|
|
|
http://www.w3.org/ as e.g.
|
|
http://www.w3.org/TR/REC-html40/HTMLlat1.ent
|
|
|
|
Input is read from stdin, output is written to stdout in form of a
|
|
Python snippet defining a dictionary "entitydefs" mapping literal
|
|
entity name to character or numeric entity.
