+The $data field is optional; it lets you pass configuration
+information (e.g. a database handle) to your hook callback.
+
+The $use_tempfile field is a flag that lets you turn on and off
+CGI.pm's use of a temporary disk-based file during file upload. If you
+set this to a FALSE value (default true) then param('uploaded_file')
+will no longer work, and the only way to get at the uploaded data is
+via the hook you provide.
+
 If using the function-oriented interface, call the CGI::upload_hook()
 method before calling param() or any other CGI functions:
 
-  CGI::upload_hook(\&hook,$data);
+  CGI::upload_hook(\&hook [,$data [,$use_tempfile]]);
 
 This method is not exported by default.  You will have to import it
 explicitly if you wish to use it without the CGI:: prefix.

+  Version 3.19
+  1. Added patch from Stephen Frost that allows one to suppress use of the temp file that is
+       created during uploads.
+  2. Fixed problem noted by Martin Foster in which regular expression meta-character terms
+       in the path information were not quoted, causing URL parsing
+       to fail on URLs that contained metacharacters (such as +).
+  3. More fixes to the url() method.
+  4. Removed "hack to fix broken PATH_INFO in MSII".
+
+  Version 3.18
+  1.  Doc typo fixes.
+  2.  Patch from Steve Peters to default the document type to match the charset.
+  3.  Fixed param() so that param(-name=>'foo',-values=>[]) sets the parameter to empty list.

   Version 3.16 Wed Feb  8 13:29:11 EST 2006
    1. header() -charset option now works even when the MIME type is not "text".
    2. Fixed documentation for cookie() function and fastCGI.
