[Bioperl-l] Bio::Search results

I have those four lines (all contained on separate lines) but it didn't work . 

I ran "gawk '{if(/^\/\/$/) {print "//\n\nHMMER 2.3.2 (Oct 2003)"} else
{print}}' my_file > whatever" on the pfam file to include a HMMER
header after the // separator for each result.

It now works fine. I still don't understand why I need to include this
header to parse the file. Although from memory don't Blast reports all
include Blast header lines to separate next results?
By the way I think that its the mailer that seems to be altering the
text in these scripts (don't know where the "=3D" came from - it's not
in my original). I'm running a standard linux (suse 9.0) using nedit
as an editor.
