// It should contain one line for every language implementation that is to be used with Vert.x

// <lang_impl_name>=[module_name:]<factory_name>
// Where:
// <lang_impl_name> is the name you want to give to the language implementation, e.g.
// 'jython'
// module_name is the (optional) name of a module that contains the language
// implementation
// if ommitted it will be assumed the language implementation is included as part of the
// Vert.x installation
// - this is only true for the Java implementation
// if included the module_name should be followed by a colon
// factory_name is the FQCN of a VerticleFactory for the language implementation
// Examples:
// rhino=vertx.lang-rhino-v1.0.0:org.vertx.java.platform.impl.rhino.RhinoVerticleFactory
// java=org.vertx.java.platform.impl.java.JavaVerticleFactory
// The file should also contain one line for every extension mapping - this maps a file
// extension to
// a <lang_impl_name> as specified above
// Examples:
// .js=rhino
// .rb=jruby
// The file can also contain a line representing the default language runtime to be used when
// no extension or
// prefix maps, e.g.
// .=java
