Fontlinge searches for font files, sorts them into folders by name and look and with human readable names, stores gathered font information in a database, generates previews and posters, finds and removes duplicates, and reunites PostScript font families. Also, Fontlinge has a Web interface to browse through your fonts. It shows detail previews and font info, provides font download as a tarball, and has the possibility to sort fonts.
Using Debian for PowerPC this semi-closed-source is not useful at all for me. Another intel-centric driver.
Re: Make a font book
There's a solution:
There you find my GPL-Software for sorting, previewing, renaming, organizing,... TrueType _and_ PostScript-Fonts.
It uses perl and MySQL for creating databases, apache and php for a webbased gui and ImageMagick for generating previews.
