Overview

TagAction - Write tagged spec description string to a tag file associated with each spec file.

The action is triggered by specs whose descriptions match the filter created with 'tags' and/or 'desc'

The action fires in the :after event, after the spec had been run. The action fires if the outcome of running the spec matches 'outcome'.

The arguments are:

action:  :add, :del
outcome: :pass, :fail, :all
tag:     the tag to create/delete
comment: the comment to create
tags:    zero or more tags to get matching
         spec description strings from
desc:    zero or more strings to match the
         spec description strings
