[CWB] Generating list of POS tags used in a corpus

[Josep M. Fontana]

Hi,

I was wondering whether there is a CQP command (or some other way in 
CWB) to generate a list of the pos tags that have been used in a corpus. 
I am exploting some corpora for which I don't have any documentation and 
I would like to have a clear idea about what tagset has been used and 
what has been encoded in the different tags.

I've searched through the last versions of the CQP language tutorial and 
the Corpus encoding tutorial but I haven't been able to find anything 
relevant. Any help will be greatly appreciated.
