aspcud - Online in the Cloud

PROGRAM:

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).
