#! /usr/bin/env python

"""

This command will pack a Panda application, consisting of a directory
tree of .py files and models, into a p3d file for convenient
distribution.  The resulting p3d file can be run by the Panda3D
runtime executable, or by the Panda3D web browser plugin.

Also see ppackage, a more powerful (but more complex) tool that can
also be used to build p3d applications, using a pdef description file.

Usage:

  %s [opts] app.p3d

Options:

  -d application_root
     Specify the root directory of the application source; this is a
     directory tree that contains all of your .py files and models.
     If this is omitted, the default is the current directory.

  -m main.py
     Names the Python file that begins the application.  This should
     be a file within the root directory. If this is omitted, the
     default is a file named "main.py", or if there is only one Python
     file present, it is used.  If this file contains a function
     called main(), that function will be called after importing it
     (this is preferable to having the module start itself immediately
     upon importing).

  -S file.crt[,chain.crt[,file.key[,\"password\"]]]
     Signs the resulting p3d with the indicated certificate.  You may
     specify the signing certificate, the optional authorization
     chain, and the private key in three different files, or they may
     all be combined in the first file.  If the private key is
     encrypted, the password will be required to decrypt it.

  -c config=value
     Sets the indicated config flag in the application.  This option
     may be repeated as necessary.

  -r package
     Names an additional package that this application requires at
     startup time.  The default package is 'panda3d'; you may repeat
     this option to indicate dependencies on additional packages.

  -s search_dir
     Additional directories to search for previously-built packages.
     This option may be repeated as necessary.  These directories may
     also be specified with the pdef-path Config.prc variable.

  -D
     Sets the allow_python_dev flag in the application.  This enables
     additional runtime debug operations, particularly the -i option
     to the panda3d command, which enables a live Python prompt within
     the application's environment.  Setting this flag may be useful
     to develop an application initially, but should not be set on an
     application intended for deployment.
