+# If we install any bundled software also install the README.md file into
+# the bundled header directory. First of all, this ensures that we always
+# have a disclaimer in place explaining where the header files come from.
+# Secondly, in rare circumstances we might end up not installing any header
+# (because they are only used internally). Because this is quite tricky to
+# figure out when setting up targets we work around this issue by simply
+# always installing something into the bundled header directory.
