I just thought of something else. Your

 
  my @array = split /:/, $line;
[download]

Will run into trouble if one day you need to code:

 
  errormessage:"couldn't open file: check permissions"
[download]

or

 
  module:LWP::Simple
[download]

so you should maybe make that

 
  my @array = split (/:/, $line, 2);
[download]

so you don't have to worry about it.
