The ncgi package provides commands that manipulate [CGI] values. These are values that come from Web forms and are processed either by [CGI] scripts or web pages with embedded Tcl code. Use the ncgi package to query these values, set and get [cookies], and encode and decode www-url-encoded values. (From the man page [http://tcllib.sourceforge.net/doc/ncgi.html])

Documentation can be found at http://tcllib.sourceforge.net/doc/ncgi.html

recently on comp.lang.tcl, [aku] mentioned that ncgi came about by starting with [Don Libes]' [cgi.tcl extension] and breaking the
code into namespaces and 3 modules.

Related modules in [tcllib] are

   * [html]
   * [javascript]
   * [htmlparse]
   * [uri]
