# INDEX build tinderbox script.  Build an INDEX for all supported FreeBSD branches
# using the latest value of OSVERSION according to the src trees.  If the build
# fails, yowl about it on ${REPORT_ADDRESS}  If not, copy the index to www.freebsd.org so
# that 'make fetchindex' sees it.
#
# When INDEX is broken, assemble the list of committers who touched files
# on the most recent 'svn update', and put those committers "on the hook".
# These committers all stay on the hook until INDEX is buildable again.
