* doxygen2man: Add option to read copyright line from the header file This should help make builds reproducible. I tried various methods of getting the date, using 'git' is no use as it could be run from a tarball, using the file date doesn't work either so this seems a reasonable compromise. * man: Use SOURCE_EPOCH to make manpage dates reproducible Also add build-aux/update-copyright.sh to keep header file copyright lines up-to-date. All code taken from knet
