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.

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 pfbtopfa utility converts PostScript Type 1 fonts in the PFB binary format into the ASCII PFA format used by X and other Unix PostScript Type 1 font uses. It can be used to convert font files, or it can be used as a traditional Unix filter, reading its input from stdin and writing its output to stdout. It can also be used as a combination of the two: read from stdin, write to a file, or read from a file, write to stdout.
