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).

- -h, --help
- print help text, and default configurations and paths
