This library is an extension to the FParsec library (http://www.quanttec.com/fparsec/).
Please see the project page or read the intro.
FParsec-Pipes does not define new parsers. Instead, its goal is to make it easier and more readable to define your own parsers.

%% .digits 4 -- '-' -- .digits 2 -- '-' -- .digits 2 -- 'T'

-|> fun yyyy mm dd h m s ->
new DateTime(yyyy, mm, dd, h, m, s)
