Source: cwirc Version: 2.0.0-7 Severity: wishlist Tags: patch User: reproducible-builds@lists.alioth.debian.org Usertags: timestamps X-Debbugs-CC: reproducible-builds@lists.alioth.debian.org Hi! While working on Debian's “reproducible builds” effort [1], we have noticed that cwirc doesn't build reproducibly. It embeds the current date into the manpage. The attached patch fixes this by using the last changelog date as a timestamp that will be embedded. Regards, Reiner [1]: https://wiki.debian.org/ReproducibleBuilds
