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".
