Yeah I've never seen --abc used as -a -b -c before, it looks quite

In unix land, the normal situation is that -- denotes a flag with one or
more
characters in it, whereas - denotes a flag with exactly one character in
it,
and flags with one character can usually be concatenated. So, --abc
denotes the
flag abc, and -abc denotes the flags a, b, and c. I don't believe that I
have
ever seen a program which took single character flags with --, and
programs
which take multi-character flags with - are rare.

In Python they use this syntax exclusively in the command-line parser.
Disallowing Windows-style or other non-GNU standard options. That's one
way to get rid of an "options" parameter I guess.
