[Bioperl-l] Sequence recognition

[David]

Hello,
Is there any module in Bioperl where you can input a sequence and
reformat it as you want. Let's say that the user gives a sequence to a
program and that the module automatically recognizes this format and
reformat it to another specific format.
For the output format I know how to do it with SeqIO but I don't know
how to recognize the format given by the user.
There is a program available on the web called readseq which does
exactly what I want but I was just wondering if such a module exists in
Bioperl.

Thanks,
David.
