Positional parses fixed-width fields.

All readers defined below will raise if they encounter unparsable content.

type header = (string * int * int) list

Specify the name, and 0-based starting position and length of each column. For example column 'foo' starting on the first character of each line and 8 characters wide would be ("foo", 0, 8). Column ranges must not overlap.

All following funtions return Error if column ranges overlap.

of_reader ?quote ?strip ?skip_lines ~sep ~header r returns a row pipe based on data read from the provided reader. sep is used as the separator between fields, and is assumed to be escaped with \ unless quote is given.
