+Package mflag (aka multiple-flag) implements command-line flag parsing.  
+It's an **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.
