void | show_usage ()
| Writes the usage line(s) to stderr.
void | write_man_page (std::ostream &out)
| Generates a man page in nroff syntax based on the description and options.

void | close_output ()
| Closes the output stream previously opened by get_output().
std::ostream & | get_output ()
| Returns an output stream that corresponds to the user's intended egg file output–either stdout, or the named output file.
Filename | get_output_filename () const
| If has_output_filename() returns true, this is the filename that the user specified.
bool | has_output_filename () const
| Returns true if the user specified an output filename, false otherwise (e.g.
