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 a file containing the problem specification in CUDF format (both
              the universe and the request)

       OUTPUT-FILE
              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.

       CRITERION
              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).

OPTIONS

       aspcud supports the following options:

       -h, --help
              print help text, and default configurations and paths

       -v, --version
              print version and license information

       -c 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

       -e ENC append  encoding  ENC  (can  be  given multiple times); if at least one encoding is
              given, then the default encoding is not used

       -p OPT append cudf2lp option OPT (can be given multiple times)

       -s SOL path to solver (clasp)

       -g GRD path to grounder (gringo)

       -l PRE path to cudf preprocessor (cudf2lp)

       -d     print debug info and 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.
