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 installers, 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 created, 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".
