24 * A NULL-terminated array of the following format:
26 * usagestr[0] - one-line synopsis (required)
27 * usagestr[1] - one-line short description (required)
28 * usagestr[2..m] - a long (possibly multi-line) description
30 * usagestr[m + 1] - an empty line separator (required if at least one
31 * option string is given, not needed otherwise)
32 * usagestr[m + 2..n] - option strings, one option per line
34 * usagestr[n + 1] - NULL terminator
36 * Options (if present) should always (even if there is no long
37 * description) be prepended with an empty line. Supplied strings are
38 * indented but otherwise printed as-is, no automatic wrapping is done.
40 * Grep for cmd_*_usage[] for examples.
