> Hi, A few months ago I had an idea for this that would be more generalisable. See https://lists.alioth.debian.org/pipermail/reproducible-builds/Week-of-Mon-20150330/001317.html for details. TL;DR is to have SOURCEDATE as an environment variable in ISO8601 format. It would be awesome for help2man to support this. At some point, debhelper can even set this environment variable automatically. X -- GPG: 4096R/1318EFAC5FBBDBCE git://github.com/infinity0/pubkeys.git
