node/tools/doc/README.md

Here's how the node docs work.

1:1 relationship from `lib/<module>.js` to `doc/api/<module>.md`

Each type of heading has a description block.


    ## module

        Stability: 3 - Stable

    description and examples.

    ### module.property

    * Type

    description of the property.

    ### module.someFunction(x, y, [z=100])

    * `x` {String} the description of the string
    * `y` {Boolean} Should I stay or should I go?
    * `z` {Number} How many zebras to bring.

    A description of the function.

    ### Event: 'blerg'

    * Argument: SomeClass object.

    Modules don't usually raise events on themselves.  `cluster` is the
    only exception.

    ## Class: SomeClass

    description of the class.

    ### Class Method: SomeClass.classMethod(anArg)

    * `anArg` {Object}  Just an argument
      * `field` {String} anArg can have this field.
      * `field2` {Boolean}  Another field.  Default: `false`.
    * Return: {Boolean} `true` if it worked.

    Description of the method for humans.

    ### someClass.nextSibling()

    * Return: {SomeClass object | null}  The next someClass in line.

    ### someClass.someProperty

    * String

    The indication of what someProperty is.

    ### Event: 'grelb'

    * `isBlerg` {Boolean}

    This event is emitted on instances of SomeClass, not on the module itself.

* Classes have (description, Properties, Methods, Events)
* Events have (list of arguments, description)
