+This is a reimplementation for Unix, by Byron Rakitzis, of the Plan 9 shell.
+The original rc was designed and implemented by Tom Duff at Bell Labs. It has
+a small feature set similar to a traditional Bourne shell, but with a much
+cleaner and simpler syntax. Among other things, this makes rc much better than
+Bourne-compatible shells at handling filenames which contain spaces. Thus,
+writing rc scripts is less error-prone than writing sh scripts.
