Overview

This implementation references ‘go-rpm-version` github.com/knqyf263/go-rpm-version Which is based on the official `rpmvercmp` github.com/rpm-software-management/rpm/blob/master/rpmio/rpmvercmp.c implementation rpm versioning schema can be found here github.com/rpm-software-management/rpm/blob/master/docs/manual/dependencies.md#versioning Details on how the caret and tilde symbols are handled can be found here docs.fedoraproject.org/en-US/packaging-guidelines/Versioning/#_handling_non_sorting_versions_with_tilde_dot_and_caret

  # Then compare version
