%description
Construct parser combinator functions, higher order functions that parse
input. Construction of such parsers is transparent and easy. Their main
application is the parsing of structured text files like those generated
by laboratory instruments. Based on a paper by Hutton (1992)
<doi:10.1017/S0956796800000411>.
