What is the difference between the OVLPL and the OVPL?
The Open Vendor Lesser Public License (OVLPL) is less restrictive than the Open Vendor Public License (OVPL). The difference is similar to the difference between the LGPL and the GPL. The OVLPL is aimed at libraries and toolkits. In essence, unlike the OVPL, you can use an OVLPL library with other open-source projects, without needing to make those projects subject to the OVLPL license.
