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.
