I just went to download PHP (5.2.6) and I noticed one of the options is "debug pack".

OK, silly question, "its for debugging", but who is it aimed at?

Us, developers using PHP, or developers of PHP?

And while you are at it can you tell me why are there seemingly two versions with the same name, but different file sizes and md5 hashes?

Can anyone fill me in?

Edit:

I did search for this and came up with nothing but lists of bug reports
