Then you can start defining options. The basic syntax is:

parser.add_option(opt_str, ...,
                  attr=value, ...)

 Each option has one or more option strings, such as "-f" or "-file", and
several option attributes that tell optparse what to expect and what to do
when it encounters that option on the command line.

单个字母的参数一般使用一个'-'号，而多字母的参数使用'--'，好象很少见到有单个'-'的多字母参数

把 -字母字母  替换成 --字母字母
再交给 optparse

把 -长字母 替换为 -- 长字母(两个-)
arg = map(lambda i: re.sub(r'(^-[a-z]{2})',r'-\1',i), arg)
再解析长字母
