psfontmgr manages PostScript fonts through the Defoma framework. It registers the name of available PostScript fonts to Defoma in postscript category, so applications which output a postscript file have all the available PostScript fonts in their font-choosing menus. . It also provides a tool named defoma-psfont-installer, which registers PostScript fonts installed in a PostScript printer. This tool benefits those who want to print a PostScript file with the printer fonts and have the printer fonts appear in a font-choosing menu.
