			== About ==
	This page is born out of discussions in Lausanne. A lot of people seem to be interested in having some standardized, documented format for dealing with time series in GRASS, so that we can deal with data (e.g. climate station, water gauges), link with models, etc., without having to come up with a custom solution each time. This could also lead to modules to help with interpolation to deal with missing values, etc.		This page is born out of discussions in Lausanne.
