[Bioperl-l] verify format

[tkd]

Hi,

I'm computer scientist and I'm new in the bioinformatics world, and 
bioperl ...

I have a small problem :

I have a file, which has to be in FASTA format, but it could be wrong. 
So, I need :
- to verify if my file is well-written in fasta format
- to verify is the content of the fasta file is protein OR nucloetides

I think there surely exists someting in bioperl to that but I didn't 
find anything.

Thank for your help
