'Size' is not the only advantage of using compiled formats over ASCII formats. They normally are also much more efficient to parse; e.g., an ASCII file format that supports comments isn't going to have any sort of index, so using any part of the file will require loading the whole file and parsing it linearly until you find what you're looking for. I'm not familiar with the PCF and BDF font formats, but I suspect this is the real reason for historically preferring PCF (though the practice of subsequently gzipping the PCF files eliminates some of the potential performance benefits). -- Steve Langasek Give me a lever long enough and a Free OS Debian Developer to set it on, and I can move the world.
