## betterbookmarks.py
# Massages a Chrome bookmarks file into an HTML file.
#
# Features:
# - Folders are ordered alphabetically
# - Bookmarks are ordered alphabetically (by description)
# - Bookmarks are shown first, followed by folders
# - Folders can be expanded or collapsed. Initially collapsed.
# - Folders are indented nicely
# - A button is provided to expand/collapse all folders
#
# Setup:
# 1) Find your browser's Bookmarks file.
# 2) Copy it into the same folder as this script
# 3) Open a terminal window; change directory to this script's folder
# 4) If any of your Bookmarks have international characters, you
#    will want to do the following:
#    set PYTHONIOENCODING=UTF-8
# 5) python betterbookmarks.py > bookmarks.html
