I am trying to get an upload of a CSV file from an upload field on a webpage. Currently the webpage is used by Mac, Windows, and Linux users. When a Mac user uploads, $/ is not set correctly so the CSV appears as a single line and gets thrown out by the system. How can I accurately figure out whether I need to update $/ to use the correct line breaks so that my CSV file gets parsed correctly. 
   
my $file = $q->upload('event_upload'); 
my $start_row = $q->param('row_start');

## Toss out lines until we hit the specified start row
if ($start_row) {
  for (1..$start_row) {
       my $garbage = <$file>;
  }
}
while (my $line = <$file>) {
### Do file stuff
}
