Tracing
-------
- With one or more comma-separated flags, traces those specific phases
- Supported flags:
  * peg       : shows tokens emitted by tokenizer
  * sync:1    : shows tokens flowing through the post-tokenizer Sync Token Transform Manager
  * async:2   : shows tokens flowing through the Async Token Transform Manager
  * sync:3    : shows tokens flowing through the post-expansion Sync Token Transform Manager
  * tsp       : shows tokens flowing through the TokenStreamPatcher (useful to see in-order token stream)
  * list      : shows actions of the list handler
  * pre       : shows actions of the pre handler
  * p-wrap    : shows actions of the paragraph wrapper
  * html      : shows tokens that are sent to the HTML tree builder
  * dsr       : shows dsr computation on the DOM
  * tplwrap   : traces template wrapping code (currently only range overlap/nest/merge code)
  * wts       : trace actions of the regular wikitext serializer
  * selser    : trace actions of the selective serializer
  * domdiff   : trace actions of the DOM diffing code
  * wt-escape : debug wikitext-escaping

--debug enables tracing of all the above phases except Token Transform Managers

Examples:
$ node parse --trace pre,p-wrap,html < foo
$ node parse --trace sync:3,dsr < foo

Debugging
---------
- With one or more comma-separated flags, provides more verbose tracing than the equivalent trace flag
- Supported flags:
  * pre       : shows actions of the pre handler
  * wts       : trace actions of the regular wikitext serializer
  * selser    : trace actions of the selective serializer

[subbu@earth tests] node parse --dump=help
Dumping state
-------------
- Dumps state at different points of execution
- DOM dumps are always doc.outerHTML
- Supported flags:
  * tplsrc            : dumps preprocessed template source that will be tokenized
  * dom:post-builder  : dumps DOM returned by HTML builder
  * dom:pre-dsr       : dumps DOM prior to computing DSR
  * dom:post-dsr      : dumps DOM after computing DSR
  * dom:pre-encap     : dumps DOM before template encapsulation
  * dom:post-encap    : dumps DOM after template encapsulation
  * dom:post-dom-diff : in selective serialization, dumps DOM after running dom diff

--debug dumps state at these different stages

Examples:
$ node parse --dump dom:post-builder,dom:pre-dsr,dom:pre-encap < foo
$ node parse --trace html --dump dom:pre-encap < foo
