[EMBOSS] Parameter discrepency

[Ryan Golhar]

I'm using needle to align sequences...I need the output in fasta format.
Looking the the tfm for needle, under associated qualifers for -outfile,
the parameter -aformat3 is listed. 

Further below is the section on Output file format which lists the
parameter 
as -aformat.  

I tried -aformat and that seems to work, so does -aformat3.  Is one of
them not supposed to be there or just a carryover from an older version
of emboss?  The docs talk about one version but use the other in the
example...
