Trying to upload files

I want the user to be able to upload files to my site. I know how to make the input field to allow the user to browse for the file but don't know how to actually load it into a directory.

What CGI do I need to write to do this??
Is there someting in the CGI.pm library to do this??

there sure is: perldoc CGI

print $query->filefield(-name=>'uploaded_file',
-default=>'starting value',
-size=>50,
-maxlength=>80);

print $query->filefield 'uploaded_file','starting value',50,80);
