New submission from mirabilos <t...@debian.org>:
The argparse documentation and tutorial as well as its default option groups
speak of "positional arguments" and "optional arguments". These are not used
correctly, though.
Elements of the argument vector (past item #0) are distinguished as options and
(positional) arguments.
Options are either flags (ls "-l", cmd "/c") or GNU long options ("--help").
They are usually optional ("[-h]") but may be mandatory (such as -o/-i/-p for
cpio(1)). They may have option arguments (cpio(1) "-H format").
Arguments (also called positional arguments) may be mandatory ("file") or
optional ("[file]"). They are also called operands (mostly in POSIX, not very
common).
The argparse documentation confused the hell out of me at first because I only
saw argument documentation and could not find option documentation…
