+=item NewFile1
+ 
+  Does all phase 1 processing of file creation:
+  Ensures that the user provides a new filename, adds proper extension
+  if needed and that the file does not already exist, if it is a html,
+  problem, page, or sequence, it then creates a form link to hand the
+  actual creation off to the proper handler.
+
+Parameters:
+
+=over 4
+
+=item   $request  - Apache Request Object [in] - Server request object for the
+               current url.
+
+=item   $username - Name of the user that is requesting the directory creation.
+
+=item   $domain   - Name of the domain of the user
+
+=item   $dir      - current absolute diretory
+
+=item   $newfilename
+                  - Name of the file to be created; no path information
+=back
+
+Side Effects:
+
+=over 4
+
+=item 2 new forms are displayed.  Clicking on the confirmation button
+causes the browser to attempt to load the specfied URL, allowing the
+proper handler to take care of file creation. There is also a Cancle
+button which returns you to the driectory listing you came from
