[gentoo-user] Syntax for masking kde:4?

[Peter Humphrey]

Hello list,

In the last few days some parts of KDE v4 seem to have been moved into the 
stable tree, but on some of my boxes I want to exclude kde:4 (but not qt:4).

What is the syntax for a single entry in package.mask to exclude the whole of 
kde:4? I did start masking each package separately, but that's far too much 
work - I'd finish up with an entry for every kde package that has a version 
4. Also, "kde:4", which seems like the right thing to specify, is an invalid 
package atom according to eix.

I can't see anything relevant in man pages or the gentoo kde configuration 
guide. Google hasn't helped me either.
