Best tool/library to download HTML page + all components

Question

I am looking for a command line tool, or a library (preferably in Perl) to download an HTML page and all its components: external CSS, external JavaScript, images, flash or other objects, etc.

I have not found a tool to do that. I could download the HTML page, and parse the HTML to find all the external links. But I'd rather not re-invent the wheel if an existing tool does that.

Answer 1

WGet may serve your needs, although I do not know about how it works with CSS.

Answer 2

wget will work easily, but ajax/xul/etc and similar issues it won't handle and for good reason.
