+
+# lua:
+# likwid's primary functionality is driven by a set of lua scripts installed in
+# /usr/bin/
+# likwid bundles lua-5.3.2, AND supports using a system copy of lua-5.2 or
+# lua-5.3, which we use. This ebuild uses the system copy of Lua instead.
+#
+# hwloc:
+# likwid bundles a MODIFIED copy of hwloc-2.0.0a1 with specific configuration
+# for CPU probing & access
+#
+# Perl:
+# likwid uses Perl to convert from an internal text format to ASM listings
+# likwid also uses perl for some installed helper scripts
+# The build system bundles some Perl modules, that are not removed at this time:
+# Parse-RecDescent
+# Template
+#
+# Python:
+# Python3 is used for one helper script, filter/json, added after 4.3.3
