We distribute the library under the GNU Library General Public License (LGPL). In short, this means if you write a program using the library, you must (offer to) distribute the source to the library, along with any changes you have made, and allow anyone to modify the library source and distribute their modifications. It does not mean you have to distribute the source to your program, although we hope you will. See the files `COPYING' and `COPYING.LIB' for the text of the GNU licenses. If you know enough about TeX to be reading this manual, then you (or your institution) should consider joining the TeX Users Group (if you're already a member, great!). TUG produces the periodical `TUGboat', sponsors an annual meeting and publishes the proceedings, and arranges courses on TeX for all levels of users throughout the world.
