Today's irritation

Software companies that don't bother stating the platform(s) their products require, the unspoken assumption being that the whole world is Bill Gates' bitch.

This is the third DITA-editing package I've checked that doesn't specify platform. I'm going to give up on links from the DITA sites and just google for DITA+Linux. Or possibly pen+paper.

Oh, but here's some Logic ...

* The pen is mightier than the sword.
* The cat¹ is mightier than the pen²
* Therefore, the cat is mightier than the sword.

¹ Sam, this morning.
² my green glittery gel-pen. Which I was using at the time. My former pen, I should say.

EDIT: Something useful for Linux users! (I bet you can't find a pattern for cuddly Bill.)
