Hi Martin;

This definitely isn't a bioperl-relevant question at all, but 'cause
I'm such a darn nice guy...

Running 'blastall' with no arguments lists all possible arguments
for BLASTing:

  -v  Number of database sequences to show one-line descriptions for
  (V) [Integer]
      default = 500

  -b  Number of database sequence to show alignments for (B)
      default = 250
Hope this helps.
