+# In general, GPLv2+ is used by programs, LGPLv2+ is used for
+# libraries.
+#
+# LGPLv2+ with exceptions is used for things that are linked directly
+# into dynamically linked programs and shared libraries (e.g. crt
+# files, lib*_nonshared.a).  Historically, this exception also applies
+# to parts of libio.
+#
+# GPLv2+ with exceptions is used for parts of the Arm unwinder.
+#
+# GFDL is used for the documentation.
+#
+# Some other licenses are used in various places (BSD, Inner-Net,
+# ISC, Public Domain).
+#
+# HSRL and FSFAP are only used in test cases, which currently do not
+# ship in binary RPMs, so they are not listed here.  MIT is used for
+# scripts/install-sh, which does not ship, either.
+#
+# GPLv3+ is used by manual/texinfo.tex, which we do not use.
+#
+# LGPLv3+ is used by some Hurd code, which we do not build.
+#
+# LGPLv2 is used in one place (time/timespec_get.c, by mistake), but
+# it is not actually compiled, so it does not matter for libraries.
