//! Test vectors from the dpkg version comparison package.
//!
//! These tests are taken from
//! [Dpkg_Version.t](Dpkg-1.20.9/source/t/Dpkg_Version.t)'s data table. I do
//! not believe the version table at the bottom is copyrightable, but in
//! the spirit of ensuring we have a clear division in case there's any licensing
//! concerns -- this is in a separate file, and not shipped in builds using
//! this library.
