This extension is like the tokenizer extension for PHP. It takes a
document comment (docblock) like this one:

/**
- information {@inlinetag}
- @tags
- */

and parses it into tokens.

The primary function is docblock_tokenize(), which accepts a string,
and returns an array of arrays of array(TOKEN, "token"). TOKEN is one
of DOCBLOCK_* constants.

docblock_tokenize() has an optional second bool parameter that
determine whether to output non-essential tokens like the /** * stuff.

docblock_token_name() takes a DOCBLOCK_* constant and returns its name

In PECL status of this extension is: %{_status}.
