I need help with SLK's license agreement: SLK is a parser generator, the generator itself is not open source but there are some open source samples. Here is a part from license agreement: ... The License grants you the right to use and modify the source code ("Source Code") contained in the Product for the purposes of evaluating, designing, developing, and testing software products, and to reproduce and distribute the Source Code, along with any modifications thereof, provided that you agree: (1) to distribute the Source Code in source or object code form and only in conjunction with and as a part of a software application product developed by you that adds significant and primary functionality to the Source Code; (2) to indemnify, hold harmless, and defend the supplier of the Product from and against any claims or lawsuits, including attorney's fees, that arise or result from the use or distribution of your software application product. ... I do not understand point (1) Do I have to publish the source of my program if I only use the generated parser? And what does 'object code' mean? FULL LICENSE AGREEMENT

We don't speek for them. To get an authoritative answer:

1. Look at the contact page on their web site.
2. Click on their email address.
3. Ask them about their intentions.
4. Keep a hard copy of their response.

That's what source code turns into after you compile it. IANAP
