seq- and jot-like enumerator
enum enumerates values (numbers) between two values, possibly further adjusted by a step and/or a count, all given on the command line. Before printing, values are passed through a formatter. Very fine control over input interpretation and output is possible.
enum is designed to be a drop-in replacement for GNU seq while still providing (almost) the same feature set jot (on BSD) provides.
