How do I add variables to attribute only files?
The software appears to be missing from the developer's website. There is no information about it or about attribute files. In this case, I recommend that you send an email to the developer asking for this information. Google Search also doesn't offer any links to user guides or something related. Use the contact info posted below to get in contact with the developer:
