+# revdep-rebuild: Reverse dependency rebuilder.
+# Original Author: Stanislav Brabec
+# Current Maintainer: Paul Varner <fuzzyray@gentoo.org>
+
+# Known problems:
+#
+# In exact ebuild mode revdep-rebuild can fail to properly order packages,
+# which are not up to date.
+# http://bugs.gentoo.org/show_bug.cgi?id=23018
+#
+# Rebuilding using --package-names mode should be default, but emerge has no
+# feature to update to latest version of defined SLOT.
+# http://bugs.gentoo.org/show_bug.cgi?id=4698
+
+# Customizable variables:
+#
+# LD_LIBRARY_MASK - Mask of specially evaluated libraries
+# SEARCH_DIRS - List of directories to search for executables and libraries
+# SEARCH_DIRS_MASK - List of directories to not search
+#
+# These variables can be prepended to either by setting the variable in 
+# your environment prior to execution, or by placing an entry in
+# /etc/make.conf.
+#
+# An entry of "-*" means to clear the variable from that point forward.
+# Example: env SEARCH_DIRS="/usr/bin -*" revdep-rebuild will set SEARCH_DIRS
+# to contain only /usr/bin
+
+# Print pre-release disclaimer to stderr
