Examples of joptsimple.BuiltinHelpFormatter

joptsimple.BuiltinHelpFormatter

A help formatter that allows configuration of overall row width and column separator width.

The formatter produces a two-column output. The left column is for the options, and the right column for their descriptions. The formatter will allow as much space as possible for the descriptions, by minimizing the option column's width, no greater than slightly less than half the overall desired width.
