Present displays slide presentations and articles. It runs a web server that
presents slide and article files from the current directory.

It may be run as a stand-alone command or an App Engine app.

Usage of present:
  -base="": base path for slide template and static resources
  -http="127.0.0.1:3999": HTTP service address (e.g., '127.0.0.1:3999')
  -nacl=false: use Native Client environment playground (prevents non-Go code execution)
  -notes=false: enable presenter notes (press 'N' from the browser to display them)
  -orighost="": host component of web origin URL (e.g., 'localhost')
  -play=true: enable playground (permit execution of arbitrary user code)

The setup of the Go version of NaCl is documented at:
https://golang.org/wiki/NativeClient

To use with App Engine, copy the tools/cmd/present directory to the root of
your application and create an app.yaml file similar to this:

    application: [application]
    version: [version]
    runtime: go
    api_version: go1

    handlers:
    - url: /favicon.ico
      static_files: present/static/favicon.ico
      upload: present/static/favicon.ico
    - url: /static
      static_dir: present/static
      application_readable: true
    - url: /.*
      script: _go_app

    # nobuild_files is a regexp that identifies which files to not build.  It
    # is useful for embedding static assets like code snippets and preventing
    # them from producing build errors for your project.
    nobuild_files: [path regexp for talk materials]

Present then can be tested in a local App Engine environment with

    goapp serve

Input files are named foo.extension, where "extension" defines the format of
the generated output. The supported formats are:
	.slide        // HTML5 slide presentation
	.article      // article format, such as a blog post

The present file format is documented by the present package:
http://godoc.org/golang.org/x/tools/present
