<< " panda3d [opts] file.p3d [args]\n"
<< " panda3d -m [opts] file_a.p3d file_b.p3d [file_c.p3d ...]\n\n"
<< "This program is used to execute a Panda3D application bundle stored\n"
<< "in a .p3d file. In the first form, without the -m option, it\n"
<< "executes one application; remaining arguments following the\n"
<< "application name are passed into the application. In the second\n"
<< "form, with the -m option, it can execute multiple applications\n"
<< "simultaneously, though in this form arguments cannot be passed into\n"
<< "the applications.\n\n"
<< "Options:\n\n"
<< " -m\n"
<< " Indicates that multiple application filenames will be passed on\n"
<< " the command line. All applications will be run at the same\n"
<< " time, but additional arguments may not be passed to any of the\n"
<< " applictions.\n\n"
<< " -t token=value\n"
<< " Defines a web token or parameter to pass to the application(s).\n"
<< " This simulates a <param> entry in an <object> tag.\n\n"
<< " -w [toplevel|embedded|fullscreen|hidden]\n"
<< " Specify the type of graphic window to create. If you specify\n"
<< " \"embedded\", a new window is created to be the parent.\n\n"
<< " -s width,height\n"
<< " Specify the size of the graphic window.\n\n"
<< " -o x,y\n"
<< " Specify the position (origin) of the graphic window on the\n"
<< " screen, or on the parent window. If you specify -1,-1\n"
<< " the default position will be used, and a value of -2,-2\n"
<< " means that the window will be centered on the screen.\n\n"
<< " -l log_dirname\n"
<< " Specify the full path to the directory in which log files are\n"
<< " to be written. If this is not specified, the default is to send\n"
<< " the application output to the console.\n\n"
<< " -n\n"
<< " Allow a network connect to the Panda3D download server, to check\n"
<< " if a new version is available (but only if the current version\n"
<< " appears to be out-of-date). The default behavior, if both -n\n"
<< " and -f are omitted, is not to contact the server at all, unless\n"
<< " the local contents do not exist or cannot be read.\n\n"
<< " -f\n"
<< " Force an initial contact of the Panda3D download server, even\n"
<< " if the local contents appear to be current. This is mainly\n"
<< " useful when testing local republishes.\n\n"
<< " -i\n"
<< " Runs the application interactively. This requires that the application\n"
<< " was built with -D on the packp3d command line. If so, this option will\n"
<< " create an interactive Python prompt after the application has loaded.\n"
<< " It will also retain the PYTHONPATH environment variable from the user's\n"
<< " environment, allowing Python files on disk to shadow the same-named\n"
<< " Python files within the p3d file, for rapid iteration on the Python\n"
<< " code.\n\n"
<< " -S\n"
<< " Runs the application with security enabled, as if it were embedded in\n"
<< " a web page.\n\n"
<< " -u url\n"
<< " Specify the URL of the Panda3D download server. This is the host\n"
<< " from which the plugin itself will be downloaded if necessary. The\n"
<< " default is \"" << _host_url << "\" .\n\n"
<< " -M super_mirror_url\n"
<< " Specifies the \"super mirror\" URL, the special URL that is consulted\n"
<< " first before downloading any package file referenced by a p3d file.\n"
<< " This is primarily intended to support pre-installing a downloadable\n"
<< " Panda3D tree on the local machine, to allow p3d applications to\n"
<< " execute without requiring an internet connection.\n\n"
<< " -p platform\n"
<< " Specify the platform to masquerade as. The default is \""
<< DTOOL_PLATFORM << "\" .\n\n"
<< " -V\n"
<< " Output only the plugin version string and exit immediately.\n\n"
<< " -U\n"
<< " Output only the plugin host URL and exit immediately.\n\n"
<< " -P\n"
<< " Output only the plugin platform string and exit immediately.\n\n";
