NAME

       aspcud - solve dependencies between packages

SYNOPSIS

       aspcud [OPTION]... [INPUT-FILE] [OUTPUT-FILE] [CRITERION]

DESCRIPTION

       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.

ARGUMENTS

       The first two command line arguments are mandatory:

       INPUT-FILE
              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.

       OUTPUT-FILE
              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.

       CRITERION
              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.

OPTIONS

       aspcud 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 used

       -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 times)

       -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
              do not cleanup temporary files

ENVIRONMENT VARIABLES

       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.
