packup: PACKage Upgradability Problem solver


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: //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
