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.
