[tex-hyphen] I am coding a mobile that uses TeX hyphen file...

[Christopher Camacho]

Hi Luke,
I am like you: I am not a lawyer and dislike this part, but I want to start a business and have to deal with it.
The GPL or GNU licence is a real problem because it states that code must be open source AND all additional code that uses the GPL licence code must also be open source.
That would mean I would have to make my product open source but as I have been working on my product since April at my own expense, I am very unwilling to do that.
I worked briefly for Samsung in Staines and they were almost paranoid about the GPL licence.
If my product makes money, I am very willing to contribute to TUG but I simply can’t afford to have my product open source.
Having gone over 44 files this morning, here is what I found:
16 lppl
13 mit
6 GPL (Czech, Hungarian, Indonesian, Irish, Latvian, Slovak)
2 BSD
6 very vague or none really.
1 missing Serbian Latin
It would be great if I could include links to as many hyphen files as possible. However, my product does not support right to left writing. That excludes Arabic and Hebrew. Are there any others? Chinese, Japanese and Korean can be written in all directions I understand so Left to Right is OK.
Serbian Latin has been removed very recently.

Kind Regards,

Christopher Camacho

Loathing and detesting anything to do with licences, I am not able to help you with your question, but it might help if you could clarify what "warning" you received about a GPL licence on some hyphen files, why "the GPL licence is a real problem", why you must "exclude all links to files with such a licence from my product", and what exactly you need to "look out for" when considering licences other than GPL.

Hello,
I am coding an app that uses Knuth-Liang algorithm for hyphenation.
I have already been in touch with Tug and was warned about GPL licence on some hyphen files.
Having worked for Samsung, I am aware the GPL licence is a real problem and I must exclude all links to files with such a licence from my product.
I know MIT licence is OK.
Is LPPL licence OK? I read terms and it looks OK, but I am not a lawyer.
Is GPL the only licence to watch out for?

Kind Regards,
