# Releases of notmuch have a two-digit version (0.1, 0.2, etc.). We
# increment the second digit for each release and increment the first
# digit when we reach particularly major milestones of usability.
#
# Between releases, (such as when compiling notmuch from the git
# repository), we let git append identification of the actual commit.
