The MIT License (also known as the X11 license or MIT X license) is a software license that was originally developed at the Massachusetts Institute of Technology. It is similar to the BSD license, which was first used for the Berkeley Source Distribution, a version of UNIX that was developed at the University of California at Berkeley (UCB). The main difference is that BSD-style licenses sometimes contain a clause prohibiting the use of the name of the copyright holder in promotions without permission.
Both the MIT and BSD licenses are considered to be more liberal than the GNU Public License (GPL), which is by far the most frequently used free software license. The reason for this is that the GPL requires that;
According to the Free Software Foundation (FSF), the MIT license should be referred to as the X11 license, because MIT has released software under a number of other licenses as well. (X11 is the current version of the X Window System, the de facto standard graphical engine for Linux and other Unix-like operating systems. It was developed at MIT.)
However, the Open Source Initiative refers to it as the MIT License, as do many other groups. It should be kept in mind that the FSF is the same organization that insists that Linux should be renamed GNU/Linux (because of the large amount of GNU software included in Linux distributions). A good compromise is to refer to it as the MIT X License.
The MIT License is not copyrighted, in contrast to the GPL, other developers are free to modify it to suit their own requirements.
The basic template of the MIT License is as follows:
