GNU TeXmacs is a free wysiwyw (what you see is what you want) editing platform with special features for scientists. The software aims to provide a unified and user friendly framework for editing structured documents with different types of content: text, mathematics, graphics, interactive content. TeXmacs can also be used as an interface to many external systems for computer algebra, numerical analysis, and statistics. New presentation styles can be written by the user and new features can be added to the editor using Scheme.
FreeType 2 is a high-quality and portable font engine that is capable of supporting several font formats (be they bitmapped or scalable) through a simple and uniform interface. Its design is modular and allows independent "font driver" modules to be added, even at runtime, to support additional formats. It also provides a high-quality anti-aliasing renderer, an innovative auto-hinting engine, and support for the following font formats: TrueType Type1, CID-Type 1, Multiple Masters Type 1 OpenType/CFF, pure CFF, and CEF Windows FNT/FON.
rxvt-unicode is a clone of the well known terminal emulator rxvt, modified to store text in Unicode and to use locale-correct input and output. It also supports mixing multiple fonts at the same time, including Xft fonts, real transparency, and an optional embedded Perl interpreter that allows you to extend your terminal easily.
acoc is a regular-expression based colour formatter for programs that display output on the command-line. It works as a wrapper around the target program, executing it and capturing the stdout stream. Optionally, stderr can be redirected to stdout, so that it, too, can be manipulated. acoc then applies matching rules to patterns in the output and applies colours to those matches.
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.
webFonts4Linux is a shell scripts that automates the process of downloading and installing Microsoft's Web Core Fonts, a collection of high-quality True Type fonts designed for use with low resolutions. webFonts2Linux exists because although these Microsoft distributes these fonts for free, strong redistribution restrictions makes it impossible to distribute a tarball or package containing them.
The fontutils package includes the programs bpltobzr, bzrto, charspace, fontconvert, gsrenderfont, imageto, imgrotate, limn, and xbfe. These create fonts for use with Ghostscript or TeX (starting with a scanned type image and converting the bitmaps to outlines), convert between font formats, etc. The package also includes the libraries libbzr.a, libgf.a, libpbm.a, libpk.a, libtfm.a, and libwidgets.a.
