NAME
aspcud - solve dependencies between packages
SYNOPSIS
aspcud 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 install-
ers, but may also be used independently.
If the tool is not able to find a solution then it prints "FAIL" to stdout.
ARGUMENTS
All three 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 cre-
ated, if it does already exist it will be overwritten without warning.
criterion
desribes the optimization criterion. The criterion is a non-empty and comma-separated list of signed function names. Each sign is
either "+" or "-", and each function name is one of removed, new, changed, notuptodate, unmet_recommends. One may also use the
macros "trendy" or "paranoid".
