NAME swizel - takes csv input, selects columns and arbitrarily selects output order OPTIONS change the field delimiter (default comma) handle trimming whitespace per field (or an arbitrary set of chars, e.g. quotes) ignore or transform a prefixed one-line header or comment (default #) [bonus points] handle numeric fields (e.g. precision or float/int conversion) OBLIGATORY while all of this can already be done with a combination of cut, sed, tr and/or awk, it's a common task when working with columnar data and could be made more intuitive and less error prone. transforming columnar data mostly boils down to clean up and basic sanity checks. good karma on this one.
