Number of Debian packages available.

[Lisi <lisi.reisz@gmail.com>]

Hello, all!
I have searched Wikipedia and the Debian wiki.  I have Googled.  I am clearly 
using the wrong search terms, although I tried rewording in sundry different 
ways.

Approximately, in round terms, how may packages are available in Debian 
(Squeeze?)
1. in main
2. in main, contrib and non-free

I have an idea of roughly 20,000 in my head, but cannot remember why I think 
it and it may be vastly out.  Nor into which of my two categories the figure 
falls, if by any miracle it is correct.

Thanks,
Lisi
