+Description: Honour SOURCE_DATE_EPOCH if available
+ Using the current date for timestamps will produce unreproducible
+ manpages. If the environment variable SOURCE_DATE_EPOCH is set,
+ as proposed by the Reproducible Builds effort [1], a deterministic
+ timestamp is avilable that can be used to embed dates.
