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".
