*	contrib/hooks: add sample post-receive hook using agefile	John Keeping	2015-08-12
	One of the most frequent questions on the mailing list relates to the idle time in the repository list. The answer to this is to use the "agefile" feature to calculate the time of the last change whenever the repository receives changes. Add a sample post-receive hook in a new "contrib" directory so that we can just point people at the repository in the future. Signed-off-by: John Keeping <john@keeping.me.uk>
