Licensing confusion

[TheCount]

There is some confusion about which license(s) apply to YAEP.

• The README states YAEP is licensed under LGPL version 2
• The copyright file states YAEP is dual licensed under GPL and LGPL, and then references /usr/share/common-licenses/(GPL|LGPL), which, in my case, are symlinks to the newest versions (3.0) of the respective licenses.
• The headers of some of the source files (e. g., yaep.c, second comment block) specifically forbid the use of the LGPL.

@vnmakarov could you please clarify:

• Which license do you want to apply to YAEP?
  • GPL?
  • LGPL?
  • GPL/LGPL dual license?
  • Something else?
• Which version(s) of the license(s) do you want to apply?
  • GPL version 2?
  • GPL version 3?
  • LGPL version 2.0 ("library" license)?
  • LGPL version 2.1 ("lesser" license)?
  • LGPL version 3.0?
  • Something else?
• What about future versions of licenses?
  • Do you want to allow later versions (the "version X, or (at your option) any later version" clause)?
  • Do you want to allow only the specified versions?
  • Something else?

I can make a pull request fixing those headers/copyright files for you once you indicate what you want.

Sorry for delay with the answer. I was too busy and also needed to think about this for some time.

After some thoughts I decided to move more restrictive license. I think MIT license would be the best for YAEP.

OK. I'm still working on revamping the build/test system. After that, I can make a pull request fixing all the license headers.
