Solve dependencies between packages
aspcud [OPTION]... INPUT-FILE OUTPUT-FILE [CRITERION]
aspcud 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 a file containing the problem specification in CUDF format (both the universe and the request)
is the pathname of a 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 no criteria is given, then the paranoid optimization criteria is chosen. To get a list of supported criteria, see the -c option of cudf2lp\|(1).
aspcud supports the following options:
print help text, and default configurations and paths
print version and license information
append clasp option OPT (can be given multiple times); if at least one clasp option is given, then default search options are not used
append encoding ENC (can be given multiple times); if at least one encoding is given, then the default encoding is not used
append cudf2lp option OPT (can be given multiple times)
path to solver (clasp)
path to grounder (gringo)
path to cudf preprocessor (cudf2lp)
print debug info and do not cleanup temporary files
aspcud uses temporary files. These are put into the folder indicated by the environment variable TMPDIR or, if not set, by the POSIX constant P_tmpdir.
aspcud has been written by Roland Kaminski and Martin Gebser.
