//==========================================------
// p4DAV.php  Implements a  Perforce WebDAV server
//==========================================------
// Derived from the open source HTTP_WebDAV_Server class (0.99.1)
// ********************************************
// Runs as a helper for Apache HTTP requests of this pattern...
//       http://[thisdomain]/p4/[Perforce path without initial //]
// Requires a directory "davroot" in the Apache document root for temporary files
// Requires the service of the Perforce command-line client P4.
// Triggered by the following directive included in Apache's conf.ini file...
//       AliasMatch ^/p4.*  [somewhere]/p4DAV.php
// Serves a single Perforce repository whose IP address is specified below
// Resides in a directory with companion files...
// 1) p4DAV.php  [this file] (heavily modified from davserver.php)
// 2) DepotServer.php  (heavily modified from FileSystem.php)
// 3) DAVServer.php  (derived with slight mods from Server.php)
// 4) Tools  (a directory, unmodified from open-source distribution) containing
//  4.1) _parse_lockinfo.php
//  4.2) _parse_propfind.php
//  4.3) _parse_proppatch.php
