[Bioperl-l] Bio::Root::IO reads URLs from -file

[Allen Day]

just commited this to cvs.  if you pass a -file arg to a Root::IO 
subclass, the following happens:

if(the file exists){
  do as before
}
elsif(the file doesn't exist, and the name looks like a url) {
  try a few times to {
    download the url to a local tempfile, and update -file to point
    to the tempfile
  }
  if(couldn't download the file){
    throw an error
  }
}

i'm open to moving urls to a special -url argument instead of overloading 
-file.  what do people think?
