psftools (tools for converting between bitmap font formats)

The PSF Tools are an attempt to do something similar to NetPBM
for simple fixed-width bitmap fonts. It supports at least these
font formats:

- Linux console .PSF/.PSFU
- X11 .BDF
- MS-DOS .CPI
- Windows .FNT and .FON
- IBM MDA (Monochrome Display Adaptor)
- BBC Micro
- ZX Spectrum
- Wyse-60
- Hercules WriteOn
- Raw bitmaps

...and can also convert fonts to XBM, PBM, C source, and human-readable
text files. psftools can also merge font files together, and transform
them in various ways (scaling, flipping, adjusting the bounding box, etc).
