Love the tools, this has been a big help in working with OTF Files.
I have a question though. I was reading the GSUB table TTX outputs into XML to figure out what OTF Feature Tags (salt, aalt, liga) exist in a font. My only problem is, depending on how intense a fonts features may be, this table can make the output of the xml to be very large. For example, I took Liza pro by Underware into ttx via: ttx -s -d and the GSUB table was 192 megs!
Is there any other way to find the OTF features from the xml, or how to limit that/compress that output?
Thanks for any help you may have..
