Bitmap Font Generator v1.14a by Andreas Jönsson (www.AngelCode.com)
----------------------------------------------------------------------------------------
This program will allow you to generate bitmap fonts from TrueType and other Windows fonts. The application generates both image files and character descriptions that can be read by a game for easy rendering of fonts.
