# The following things just need to be at the top of all configure.ac files:

# AC_INIT sets up the project metadata:
# first field is the name of the "software"
# second field is the version identifier - iso 8901 date is good if you
#   have no other versioining scheme in mind
# third field is email address for bug reports
# fourth field is the name of the package made by make dist, excluding .tar.gz
# fifth field is the project web address
