PackUP -- PACKage Upgradability Problem solver


packup [OPTIONS] input_file_name [output_file_name]


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.


-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-

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