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
