medit is distributed under GPL licence, its text you can find in COPYING.GPL file. Nevertheless, everything but several lang files (see list below) is under LGPL, see COPYING file. Portions of code are written not by me, those are clearly marked as such (copyright headers in files copied from other projects, or comments in source). Below is the list of thrid-party files/code with their copyrights and licenses. If you want to use my code and LGPL doesn't work for you because you have special clause in your license which is not LGPL-compatible, or other garbage like that, I will gladly release it under double license, or do something like that. Just tell me what exactly is needed. If you aren't too picky about legal stuff, then you can simply take code and use it in free software as you like, provided you leave the copyright and project name in there (unless it's a small portion of code of course, simple copy/paste must be free as in WTFL). This applies to all files (and only to those) which do have copyright notice inside; WTFL will work fine for the rest. Third-party stuff, for debian/copyright.
