NAME

       PackUP --  PACKage Upgradability Problem solver

SYNOPSIS

       packup [OPTIONS] input_file_name [output_file_name]

DESCRIPTION

       packup  is  a  solver  for the package upgradability problem specified in CUDF [TZ09].  It
       repeatedly invokes an optimization pseudo-Boolean solver in order to  solve  the  problem.
       By  default minisat+ [ES06] is used for that purpose but a different solver can be used by
       specifying the pertaining command line option.

       If input_file_name is '-', input is read from the standard input.  If the output_file_name
       is omitted, output is produced to the standard output.

OPTIONS

       -t     Use trendy  criterion

       -p     Use  paranoid criterion

       -u cs  Use  user  criterion cs.  A criterion is a lexicographic combination of the utility
              functions removed, notuptodate, unmet_recommends, new, and changed.  Each  of  them
              with  a  polarity ("+" for a function to maximize, "-" for a function to minimize).
              The functions are listed in decreasing order of  priority,  and  separated  by  the
              symbol   ",".   For   instance,   the   paranoid  criterion  could  be  written  as
              -removed,-changed.    For   more   details    see:    http://www.mancoosi.org/misc-
              live/20101126/criteria/

       --external-solver
              command for the external solver default 'minisat+ -ansi'

       --multiplication-string
              string between coefficients and variables when communicating to the solver, default
              '*'

       --temporary-directory DIR
              directory where temporary files are created. If this option is not given  then  the
              value  of  $TMPDIR  is  used  if  defined,  otherwise temporary files are placed in
              '/tmp'.

       --leave-temporary-files
              do not delete temporary files
