[wp-hackers] readme.txt: "Requires PHP 5 tag"

Most of my plugins require PHP5+ 
<http://wordpress.org/extend/plugins/profile/aaroncampbell>. Notice that 
I add "Requires PHP5" right into the main plugin description, which 
helped a lot. Also, make some sort of canned response for the questions 
you get similar to this:

The plugin requires PHP 5 and you’re running PHP 4. Most hosts offer 
PHP5 but you probably have to enable it in your control panel, through 
.htaccess, or by asking them.

As for switching to PHP 5, there's been rumors of switching in 3.0, but 
I'm sure that'll be based on stats collected. I think Matt said that 
they already have 80+% of WordPress installs using PHP5+, but he didn't 
know the exact number. Either way, it's definitely been discussed to 
death on this list.
