/** The [[stage]] package provides an implementation of the FIRRTL compiler using the [[firrtl.options]] package. This
* primarily consists of:
* - [[FirrtlStage]], the internal and external (command line) interface to the FIRRTL compiler
* - A number of [[options.Phase Phase]]s that support and compartmentalize the individual operations of
* [[FirrtlStage]]
* - [[FirrtlOptions]], a class representing options that are necessary to drive the [[FirrtlStage]] and its
* [[firrtl.options.Phase Phase]]s
* - [[FirrtlOptionsView]], a utility that constructs an [[options.OptionsView OptionsView]] of [[FirrtlOptions]]
* from an [[AnnotationSeq]]
* - [[FirrtlCli]], the command line options that the [[FirrtlStage]] supports
* - [[FirrtlStageUtils]] containing miscellaneous utilities for [[stage]]
