All Spamihilator licenses are public. Hence you can create verbatim copies to use them in other programs, but you must not change the licenses’ texts.

Spamihilator’s main license is called the Spamihilator License. The Plugin-SDK (Software Development Kit) uses a modified Spamihilator License.

This license can be applied to Freeware programs, which should be distributed for free. The distributor must not charge for the software! This is a major difference between this license and the GNU General Public License.

If the program’s author publishes its source code, it will be prohibited to modify the code or use it in another Software.

The full license follows:

Spamihilator License 1.0 (English)
Spamihilator-Lizenz 1.0 (German)

The Plugin-SDK license is based on the Spamihilator License, but there is one difference: Source code published along with the Plugin-SDK can be used to create new plugins. These plugins must be free of charge.

The modified license text follows:

Spamihilator Plugin-SDK License 1.0 (English)
