aspcud - solve dependencies between packages
solves package installation/removal/upgrade problems expressed in
the CUDF format. It is intended to be called by package installers, but may
also be used independently.
If the tool is not able to find a solution, then it writes "FAIL" to
the output file.
The first two command line arguments are mandatory:
- is the pathname of the file containing the problem
specification in CUDF format (both the universe and the request). If
absent, the specification is read from stdin.
- is the pathname of the file into which the solution will be
written in CUDF output format. If the file does not exist it will be
created, if it does already exist it will be overwritten without warning.
If absent, output is written to stdout.
- selects the optimization criterion. To get a list of
supported criteria, see the -c option of cudf2lp(1). If
absent, the paranoid criterion is used. Note that the criterion can be
passed via option --criterion as well.
supports the following options:
- -h, --help
- print help text, and default configurations and paths
- -v, --version
- print version and license information
- -c, --criterion CRIT
- set the optimization criterion
- -s, --solver-option OPT
- append clasp option OPT (can be given multiple times); if
at least one clasp option is given, then default search options are not
- -g, --grounder-option OPT
- append gringo option OPT (can be given multiple times)
- -e, --encoding ENC
- append encoding ENC (can be given multiple times); if at
least one encoding is given, then the default encoding is not used
- -p, --preprocessor-option OPT
- append cudf2lp option OPT (can be given multiple
- -S, --solver SOL
- path to solver (clasp)
- -G, --grounder GRD
- path to grounder (gringo)
- -P, --preprocessor PRE
- path to cudf preprocessor (cudf2lp)
- -V, --verbosity N
- set the verbosity level
- -d, --debug

the environment variable TMPDIR or, if not set, by the POSIX constant
