Cleaning up fonts

In the Mac postscript world, you have a bitmap suitcase which can contain bitmaps and kerning information for a font or family of fonts. However, you still need a postscript font file for each font (one for bold, one for regular, one for italic, one for bold italic). While the mac font suitcase allows you to throw all of the bitmaps and metrics into one suitcase, no such possibility is allowed for traditional postscript font files. That is one of the advatages that came about through the use of Truetype and later Opentype fonts. All the vector imaging, bitmaps, metric, and hinting could all happily sit inside a single file. However, frequently the different styles (Regular, Italic, Bold, etc.) still frequently sit in different files.
