I recently fixed this in bioperl-live when I bumped into that feature
missing. I didn't bother to update the bioperl-hmmer3 repository.
Perhaps it should be deleted to avoid the confusion.

Also, in bioperl-live, the Bio::SearchIO::hmmer parser now supports
hmmer2 and hmmer3 parsing, but by all means go for the specific parser
class if you know the version of hmmer result you're loading. :)

On a side note, even though you're probably aware of this... HMMer3 only
does local alignments, so it's not really good for domain extraction. It
is very fast, but if your software uses a profile based search to
extract specific amino acid motifs HMMer3 might let you down.
Just as a caveat that has bitten me recently.

Cheers,
Kai
