As soon as a proper set of test cases are ready I plan on putting this on
cpan, so suggestions for a better name accepted. The X is 1/3 of SAX,
which was slightly a model for this.
The parser accepts a mime message line by line, and dispatches the data to
handler methods that you provide. The data is categorized in the process
but neither altered nor otherwise parsed in any way. Some miminal
handlers are provided that can be used as examples or base classes. I
might provide one or greater more-functional handler base classes later.
