A copy of the gradle wrapper ported for use with maven 

Lightly touched to better mesh with current maven builds. (some of which my not have been necessary in hind sight) 

Test it out with this build, run: "./mvnw clean install" at the root of this repo
This will download, install, and run maven 3.0.5 (as configured in maven/wrapper/maven-wrapper.properties)

NOTE: windows batch file is NOT tested


TODO: 
* Possibly extract these bits out into something both gradle and maven (and others) can use
* Port gradle IT's to this build
* See if anyone is interested in this project

/**
* <p>
* A command-line parser which supports a command/sub-command style command-line interface. Supports the following
* syntax:
* </p>
*
* <pre>
* &lt;option>* (&lt;sub-command> &lt;sub-command-option>*)*
* </pre>
* <ul>
* <li>Short options are a '-' followed by a single character. For example: {@code -a}.</li>
* <li>Long options are '--' followed by multiple characters. For example: {@code --long-option}.</li>
* <li>Options can take arguments. The argument follows the option. For example: {@code -a arg} or {@code --long arg}.</li>
* <li>Arguments can be attached to the option using '='. For example: {@code -a=arg} or {@code --long=arg}.</li>
* <li>Arguments can be attached to short options. For example: {@code -aarg}.</li>
* <li>Short options can be combined. For example {@code -ab} is equivalent to {@code -a -b}.</li>
* <li>Anything else is treated as an extra argument. This includes a single {@code -} character.</li>
* <li>'--' indicates the end of the options. Anything following is not parsed and is treated as extra arguments.</li>
* <li>The parser is forgiving, and allows '--' to be used with short options and '-' to be used with long options.</li>
* <li>The set of options must be known at parse time. Sub-commands and their options do not need to be known at parse
* time. Use {@link ParsedCommandLine#getExtraArguments()} to obtain the non-option command-line arguments.</li>
* </ul>
