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

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.
