-Package mflag (aka multiple-flag) implements command-line flag parsing.  
-It's a **hacky** fork of the [official golang package](http://golang.org/pkg/flag/)
-
-It adds:
-
-* both short and long flag version  
-`./example -s red` `./example --string blue`
-
-* multiple names for the same option  
-```
-$>./example -h
-Usage of example:
-  -s, --string="": a simple string
-```
-
-___
-It is very flexible on purpose, so you can do things like:  
-```
-$>./example -h
-Usage of example:
-  -s, -string, --string="": a simple string
-```
-
-Or:  
-```
-$>./example -h
-Usage of example:
-  -oldflag, --newflag="": a simple string
-```
-
-You can also hide some flags from the usage, so if we want only `--newflag`:  
-```
-$>./example -h
-Usage of example:
-  --newflag="": a simple string
-$>./example -oldflag str
-str
-```
-
-See [example.go](example/example.go) for more details.
