perl regex: cant understand what /^#/ is supposed to be matching

Got a script which Im trying to debug but I cant figure out the meaning of this regex and googling "caret" and "pound" isnt helping.

$line !~ /^#/

Not a complicated question I'm sure but I'm locked away from all my perl books until after xmas!

I know that the !~ means 'doesnt match...' of course!

This is checking for all lines that do not start with "#". Typically comments in many programming language.

Caret is beginning of line. # is a #. It's looking for non-comment lines (and assuming comments start in the first column, or at least at the beginning of whatever line is).
