# Manpages use SOURCE_DATE_EPOCH to determine what date to write.
# Generally, this is sane. However, for binNMUs the source date is set
# to buildd's build start time. In effect, as rebuilds can span
# multiple days, the resulting manpages differ in file contents.
# This causes a file conflict for M-A:same.
#
# To ensure manpages match across binNMUs, we must set a custom
# revision date on AsciiDoc documents. We copy ${source:Version} logic
# of stripping the `+bN` suffix for this.
