+build_toolchain.sh
+~~~~~~~~~~~~~~~~~~
+This is the work horse. It'll (try to) build a toolchain. This is done by:
+
+	- Copy current CVS repos
+	- Update the local copies if a timestamp was specified
+	- Apply patches if you didn't ask for omitting this step
+	- configure & build & check & install binutils
+	- configure & build & check & install first-stage GCC
+
+This script knows quite some command line arguments. Maybe call it once with
+--help...  The last argument is the target to build for, which defaults to
+vax-linux.
+

 This script will update all your checked-out upstream CVS sandboxes to
