The Simputer General Public License , or the SGPL is a hardware distribution copyright public license Drafted SPECIFICALLY for the purpose of distributing Simputers . As a license it has been loosely modeled on the GPL but in substance it is very different.
The Simputer specifications are released under the terms and conditions of the SGPL. This license permits the user to build a Simplifier for non-commercial purposes. Any modifications made to the Simplified Specifications may be used exclusively by the person making the modifications with no obligation to release the same to the public domain. However, within 12 months from the date of the first public meeting of the Simplified Trust,
The Simputers manufactured under the SGPL are required to be certified by the Simputer Trust before they are allowed to be sold under the Simputer trademark. In order to be certified they must fulfill the Core Simputer Specifications as disclosed on the simputer website.
All Simputers developed under the specifications must be distributed under the same terms as the SGPL.
