Read about rc.  [0] This explanation of it is worth a read, espe-
cially  Section 28 ``Design Principles''. Note also the perfectly
simple implementation of the man command (Section 26).

There's one thing in the paper I haven't understood (Section 27):

     fn read{
             $1=`{awk '{print;exit}'}
     }

Why is awk used here? If I need to cut after the first line,  I'd
rather  use  ``sed q''. It seems unlikely that this use of awk is
by accident.



Found this (old) list of  software  patents.   [1]  It's  fun  to
scroll  through it and read a bit here and there.  The search for
Dennis Ritchie is obvious, but there's also  a  note  on  rms  in
there.
