+# IFACE is the subdirectory of /etc/env.d/ that eselect config files are stored
+# in for these packages.
+#
+# There is a file installed at /etc/env.d/$IFACE/$libdir/config containing the
+# CURRENT variable, which is set to the current eselect setting. Also, each
+# implementation installs a single file at /etc/env.d/$IFACE/$libdir/$implem.
+# This file contains a list of symlinks to be created in "source destination"
+# format. You must use relative symlinks. In other words, "source" must be
+# relative to "destination" but "destination" must be absolute. You may have
+# comments in the symlink map file -- any line containing a '#' is considered
+# a comment. One caveat about the symlink map -- instead of using "lib" or
+# "lib64" etc, you must use @LIBDIR@.
