TYM (Typo Manager) is software for managing fonts in formats like .OTF (OpenType), .TTF (TrueType), and .PFA/.PFB (Typo1). It allows you to add or "link" fonts, activate or deactivate them, and delete them. It also handles the "group font" function and stores several fonts inside one file.
Gentium is a typeface family designed to enable the diverse ethnic groups around the world who use the Latin script to produce readable, high-quality publications. It supports a wide range of Latin-based alphabets, and includes glyphs that correspond to all the Latin ranges of Unicode.
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.
The t1utils package contains six programs that manipulate PostScript Type 1 fonts. There are programs that change PFB (binary) fonts into PFA (ASCII) format (and back), that translate fonts into a disassembled human-readable format (and back), and that translate Macintosh Type 1 fonts into PFB or PFA (and back).
