<h3>Log Message</h3>
<pre>contrib: add port-checkmirrors, a script I wrote a while a go to check the integrity of distfiles on mirrors
I was told base could already do that using `distcheck`, but I've just written
the manpage for distcheck and read its source code – it doesn't even verify the
checksums, so this script may be helpful after all.</pre>
