 licensed under the GPL 3 or later.
 
 It's designed to check build logs generated by Debian's dpkg-buildpackage (or
-tools using dpkg-buildpackage like pbuilder or the official buildd build logs)
-to help maintainers detect missing hardening flags in their packages.
+tools using dpkg-buildpackage like pbuilder or sbuild (which is used for the
+official buildd build logs)) to help maintainers detect missing hardening
+flags in their packages.
 
 Only gcc is detected as compiler at the moment. If other compilers support
 hardening flags as well, please report them.
 
 If there's no output, no flags are missing and the build log is fine.
 
+See F<README> for details about performed checks, auto-detection and
+limitations.
