NAME
       rc - shell

SYNOPSIS
       rc [-deiIlnopsvx] [-c command] [arguments]

DESCRIPTION
       rc is a command interpreter and programming language similar to sh(1).
       It is based on the AT&T Plan 9 shell of the same name.  The shell
       offers a C-like syntax (much more so than the C shell), and a powerful
       mechanism for manipulating variables.  It is reasonably small and
       reasonably fast, especially when compared to contemporary shells.  Its
       use is intended to be interactive, but the language lends itself well
       to scripts.

OPTIONS
       If     is present, commands are executed from the immediately following
              argument.  Any further arguments to rc are placed in Thus:

Update mandoc in base to 1.13.3?
