This is just yet another web spider, which allows you to fetch content you need recursively.

To start you should specify one or more URLs which will be fetched and parsed.
The URLs fetched from the html files will added to the queue, downloaded, parsed and so on.

You should specify priority filters, each one is an regexp and an integer (either positive or negative).
These filters will be applied to every URLs parsed from downloaded html files, sum up to priority those
numbers where regexp matches.
URLs will be downloaded starting from the highest priority down to 1.
URLs with priority zero or below will be not downloaded.
Example of the priority filters:
    ".+Map.+" ->  +2
    ".+Enum.+" -> +1

You may specify regexp filters for URL-to-path/filename conversion.
Example:
    "docs\.oracle\.com" -> "DOCS"
    "\?" -> "_"

Also you may specify maximum recursion depth, 0 for infinite.
Default depth is 3.
