I've decided to install drupal to manage the content on my website, and I'm (slowly) migrating the content across.

I'm doing it by taking the HTML from each page from my old home page and creating new pages in drupal using the content.

The old HTML has (relative) links in it, which no longer work under drupal (not surprisingly). I ought to go through and fix up the links to point at the other pages correctly (once I've imported those pages).

So, can anyone point me at a good tool that will spider my website, looking for broken links?
