License

Short Summary

In short, OpenPKG is fully Open Source software, although it is, as a whole, not covered by a single Open Source compliant distribution license. Instead is is covered by its own (MIT-style) license plus the union of all vendor licenses from the contained software.

Long Description

As mentioned, the license issue of OpenPKG is two-fold because OpenPKG technically consists of two parts: the packaging facility itself and the packaged vendor software.

The parts the OpenPKG Project wrote, i.e., all the 125,000 lines of package specifications, the additions scripts and add-ons, etc., are placed under a simple MIT-style Open Source distribution license:

All other parts, i.e., all the vendor supplied software on which OpenPKG is based and which OpenPKG packages, is still kept and re-distributed under the original license as given out by the vendors. In our case (because OpenPKG packages only Open Source software) these are at least all OSI approved licenses. Over 80% of all those packages are covered by the GPL, LGPL, BSD-style or MIT-style licenses.
