# PyDemos2.pyw
# Programming Python, 2nd Edition (PP2E), 1999--2001
# Version 2.0, 03/01: add source-code file viewer buttons.
#
# Launch major Python+Tk GUI examples from the book, in a
# platform-neutral way. This file also serves as an index
# to major program examples, though many book examples aren't
# GUI-based, and so aren't listed here (e.g., see the Linux
# gcc build scripts in the examples root directory for C
# integration program pointers). Also see:
#
# - PyGadgets.py, a simpler script for starting programs in
# non-demo mode that you wish to use on a regular basis
# - PyGadgets_bar.pyw, which creates a button bar for starting
# all PyGadgets programs on demand, not all at once
# - Launcher.py for starting programs without environment
# settings--finds Python, sets PYTHONPATH, etc.
# - Launch_*.py for starting PyDemos and PyGadgets with
# Launcher.py--run these for a quick look
# - LaunchBrowser.py for running example web pages with an
# automatically-located web browser
# - README-PP2E.txt, for general examples information
#
# Internet-based demos live here:
# http://starship.python.net/~lutz/PyInternetDemos.html
# but this program tries to start a browser on the main web pages
# automatically, either on the site above or on local page files.
# Additional program comments were moved to file PyDemos.doc.txt
