License Index

In the lists below, a parenthesized expression following a license name is its SPDX short identifier, if one exists, except for two items in the first list (GNU General Public License and GNU Lesser General Public License). For these, the parenthesized expressions ("GPL" and "LGPL" respectively) are the common non-version-specific names of these licenses today (note also that the full name of the first version (2.0) of the LGPL is the GNU Library General Public License). There is no non-version-specific SPDX short identifier for the GPL and LGPL.
