# Pangrammer Helper
# By Mark Simonson, v. 1.1, March 13, 2012
# Thanks to Frederik Berlaen for help with hooking up to Space Center

# Simple Python version of a Flash/ActionScript "app" I first did in 2003: http://www.ms-studio.com/Animation/pangrammerhelper.html

# Purpose is to help you write pangrams--sentences that contain all the letters of the alphabet.

# Type in the window. The alphabet will shrink as you use up the letters. Current pangram length displayed at bottom.
# If you have a Space Center window open, its current text will be used and updated as you compose your pangram.

# Note: It doesn't do anything with spelled out glyph names (e.g., "/space" or "/exclam"). 
#       It's only designed to work with literal text you can type directly.
#       Non-alphabetic characters are not included in the count for pangram length.
