License Agreement

qDecoder is a Free Software. And qDecoder is distributed under the GNU Lesser General Public License since the version of 6.0(May 8, 2000).

Free software is a matter of liberty(in other word, freedom), not price. So, the purpose of this License is to make a software free to assure everyone the effective freedom to copy and redistribute it, with or without modifying it, either commercially or non-commercially.

The GNU Project provides two principal licenses for libraries for Free Software. One is the GNU Lesser General Public License (Simply Lesser GPL or LGPL) and the other is the ordinary GNU General Public License (Simply GPL). Using the Lesser GPL permits use of the library in proprietary programs and using the ordinary GPL for a library makes it available only for free programs.

The GNU group advises not to use GNU Lesser GPL because it does less to protect the user's freedom than the ordinary GPL. It's right, Lesser GPL is not a strong copyleft license. But in case of qDecoder, permitting of linking with non-free modules can bring some kinds of other advantages to users. That's why qDecoder has been distributed under Lesser GPL.

SUMMARY: qDecoder is a Free Software and distributed under GNU Lesser General Public License. This is a free software license, but not a strong copyleft license, because it permits linking with non-free modules. It is compatible with the GNU GPL.

NOTE: It's very good idea to use one of GNU Licenses for your free software. It will protect your rights and future problems.
