Currently it basically takes the existing categories a port is in, plus
the words which constitute the port's COMMENT.  Then it applies a number
of heuristics, most significantly stemming and filtering out the common
"stopwords" like "a", "the", and so on.  And then there is of course a
cutoff for those resulting tags which are too rare (otherwise the number
of resulting tags in the tagcloud would explode;  it is already pretty
bad as it is, with 815 tags).

Since mail/dovecot does not mention "maildir" in it's COMMENT, no tag
for it.  I was thinking about parsing the pkg-descr file as well, but I
was afraid it will explode the number of tags even more.  Possibly I was
mistaken, it would be good to experiment with this approach.

Failing taking into account pkg-descr, one can clearly see why a "social
collaboration" mode could produce higher quality results, since at least
one person (you) would make sure that mail/dovecot is tagged with
"maildir".  :-)
