[BioRuby] Parse string containing GenBenk file?

[Karsten Temme]

Can anyone point me to a method for creating a Bio object from a
string that contains a Genbank file?

For example, I have a Genbank file and its contents have been read
into a single string.  I am unable to use Bio::FlatFile.auto(string)
to create a Bio object.

Thanks for the help,
Karsten
