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
