Bug#1122226: bibtexparser: please make the build reproducible

[Chris Lamb]

Source: bibtexparser
Version: 2.0.0b5+really1.4.3-1
Severity: wishlist
Tags: patch
User: reproducible-builds at lists.alioth.debian.org

Hi,

Whilst working on the Reproducible Builds effort [0], we noticed that
bibtexparser could not be built reproducibly.

This is because if the tests are run or not, the mtimes of various files
are changed via a "cp" call. A patch is attached that uses "cp -a" to
also copy the (deterministic) source modification times.
