Is license “BSD” equal to BSD-3 license
On the package description page (e.g. http://wiki.ros.org/actionlib) I often find the information, that the packages has a BSD license. If it contains a license file it is possible to find out which version of the BSD-license. Or it is written in the Source code.
Until know I just found BSD-3 license and also the link for BSD in the license overview page (https://docs.ros.org/diamondback/api/...) opens the BSD-3 description.
So if is written “License: BSD” on the package description page, does it mean it is a BSD-3 license or could be any version of the BSD license?
According to the specification for the tag that is not necessarily a conclusion you can draw I believe.
It is likely that many packages actually use the 3-clause, but there is no requirement for that.
