Hi, I'm writing you on behalf of the Debian Med team which is a group inside Debian with the objective to package free software with relevance in biology and medicine for official Debian. We are about to create a debian package from fasta3 as you can see on our so called tasks biology page[1].
According to the Debian Free Software Guidelines[2] which are widely accepted as Open Source definition the current license of some files such as src/smith_waterman_sse2.c and src/glo[bc]al_sse2.[ch] is not free since it forbids free use of the software in commercial products. I wonder whether you might consider changing the licensing to some free license like GPL, BSD or MPL - just anything that has no such restriction to non-commercial use and use of modified code. You might like to know that several other authors of biologic software recently switched to free licenses (may be most prominently phylib). The advantage for you inside Debian would be a higher visibility of fasta3 (since we distribute it with metapackages) and a way better quality assurance since Debian is running several tools to automatically detect problems inside the distributed software. Kind regards and thanks for your cooperation Alex [1] http://blends.debian.org/med/tasks/bio#fasta3 [2] https://www.debian.org/social_contract#guidelines
