+# Package-settable variables:
+#
+# PREPEND_PATH
+#      A space-separated list of path names. All directories that are
+#      added to this list are added to the PATH environment variable,
+#      in reverse order. To add a directory at the very front of the
+#      PATH, append to this variable after including bsd.prefs.mk and
+#      right before including bsd.pkg.mk.
+#
+#      The modified PATH is available in all {pre,do,post}-* targets,
+#      as well as the configure scripts and invocations of the make
+#      targets in the package itself.
