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 following command-line arguments are accepted:
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.
