[Bioperl-l] UCSC database -> GFF

[Allen Day]

the problem is that there is no event handling with bio::das (or wasn't
the last time i had a look), so you don't get any objects until you've
slurped up the whole xml file.  this means that if you want, say, all the
EST alignments of chrX, you're going to run out of memory before you have
a chance to dump as gff.
