  16 =head1 Put Extension
  17
  18 This module allows you to upload wiki pages using the PUT request
  19 method. For example:
  20
  21     echo test | curl -T - http://www.emacswiki.org/cgi-bin/test/Mu
  22
  23 This will replace the Mu page with "test".
  24
  25 Note that you cannot use an URL that will be rewritten by Apache
  26 mod_rewrite as the target for your PUT request. Apparently mod_rewrite
  27 only works reliably for GET requests.
