    TTFReplaceTable [-t table] [-d deletelist] infontfile indatafile outfontfile

Inserts the named table into a TrueType font file and writes the new font
to a file. -t identifies which table to replace (default 'TSIV'). 

-d specifies an optional list of tables to delete from the font. Argument
should be a comma-separated list of table tags (default 'TSID,TSIP,TSIS').

Example:  TTFReplaceTable -tVTIS SomeFont.ttf out.txt OutFont.ttf
