Description

The engine tag is now able to check any of Cordova components's version so it's time to implement the OS/SDK version scripts. This will allow plugin authors to specify what version of OS/SDK is needed using the <engine> tag in the plugin.xml.

eg,
<engines>
<engine name="apple-xcode" version=">=4.6.3"/>
<engine name="apple-ios-sdk" version=">=6.1"/>
<engine name="android-sdk" version=">=17"/>
</engines>

These scripts will be listed in the default engines within Plugman so that a user may easily reference them in the engine tag without having to provide a location/platform attribute in the engine tag:
