       guru - System administration

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

       guru is a sophisticated program synthesis and system main­
       tenance tool developed after midnight in numerous  univer­
       sity  computing  labs.   It  is  based  on the famous LISP
       Hacker system, 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 solution is  gener­
       ated  or  the  user community has learned to live with the

       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 idle.

       If the standard input is empty, guru uses its program syn­
       thesis capabilities to generate a selection of screen edi­
       tors, X widgets, compilers, sundry  games  and  the  occa­
       sional diatribe.

       -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 terminate.

       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 generated are  undocumented.   The
       lucidity,  politeness, relevance and language of the occa­
       sional 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.
