[Bioperl-l] Download sequence by genomic location

[Peng Yu]

I could download a sequence by location at genome browser.

http://genome.ucsc.edu/cgi-bin/hgc?hgsid=166347358&o=38129163&g=getDna&i=mixed&c=chr13&l=38129163&r=38153298&db=mm9&hgsid=166347358

I know that there are ways to get the sequence. But I don't see a way
to get the sequence by location. Could anybody let me know if there is
such a function in bioperl?
