       guru - System administration

       guru [ -e program ] [ -f ] [ -p target ]

       guru is a sophisticated program synthesis and system maintenance tool developed after mid-
       night in numerous university computing labs.  It is based on the famous LISP  Hacker  sys-
       tem,  used  to  develop	AI  programs on TENEX.	guru reads a problem description from the
       standard input.	An innovative and occasionally correct solution is generated and  written
       to  the	standard output.  Typically, guru is invoked repeatedly until an acceptable solu-
       tion is generated or the user community has learned to live with the problem.

       The bugreport mechanism sometimes invokes guru.	In this case guru executes at a  priority
       inversely  proportional	to  the reported urgency of the bug.  Feature enhancements run at
       high priority whereas critical problems are fixed only when the machine would otherwise be

       If the standard input is empty, guru uses its program synthesis capabilities to generate a
       selection of screen editors, X widgets, compilers, sundry games and  the  occasional  dia-

       -e program
	       New  features  are  added to an existing program.  This option should be used with
	       caution as the enhanced program may behave unpredictably or not at all.

       -f      Reconstructs filesystems after a crash.

       -p target
	       Ports the entire system on which guru is executing to target,  preferably  a  RISC
	       machine.   This	is an extremely time consuming operation and is not guaranteed to

       If more than one option is specified, guru may thrash.  Each copy of guru has its own  set
       of unique, additional and undocumented options.

       YAPS: Yet another Program Synthesiser by S C Johnson.

       Inherent  design limitations prevent guru from synthesising comments.  The programs gener-
       ated are undocumented.  The lucidity, politeness, relevance and language of the occasional
       diatribe vary considerably.

       The  only  diagnostic is an occasional ``I deserve a raise'' - which may be ignored albeit
       doing so may provoke ``I resign'' - an unrecoverable error.

       Sending the output of one guru into another can produce quite startling results.
