Add support for --help and --helpfull
tep opened this issue · comments
The default usage message generated by the --help flag should only show flags registered by the caller of Init() (or, optionally, by packages at or below the caller's package path). The full and complete usage message should only be available when --helpfull is issued.
NOTE: Will need to investigate whether the neighboring package path of a program's main package is actually available via reflection (or similar).
