Boxes is a text filter that can draw any kind of box around its input text. Box design choices range from simple boxes to complex ASCII art. A box can also be removed and repaired, even if it has been badly damaged by editing of the text inside. Since the generated boxes may be open on any side, the program can also be used to create regional comments in any programming language. New box designs of all sorts can easily be added and shared by appending to a free format configuration file. In addition to being a command line tool, Boxes integrates well with any text editor that supports filters.
The cb2Bib is a tool for rapidly extracting bibliographic references from email alerts, journal Web pages, and PDF files. It facilitates the capture of single references from unformatted and non standard sources. Output references are written in BibTeX. Article files can be easily linked and renamed by dragging them onto the cb2Bib window. Additionally, it permits editing and browsing BibTeX files, citing references, searching references and the full contents of the referenced documents, inserting bibliographic metadata to documents, and writing short notes that interrelate several references.
Change is a non-interactive text editor, similar to sed, but much easier to use. It works by substituting a specified target pattern in the source text with another specified text pattern. It can operate on multiple files specified on the command line, or it can operate upon stdin/stdout in filter mode.
cw is a non-intrusive real-time ANSI color wrapper for common Unix-based commands. It is designed to simulate the environment of the commands being executed, so that if a person types 'du', 'df', 'ping', etc. in their shell it will automatically color the output in real-time according to a definition file containing the color format desired. It has support for wildcard match coloring, tokenized coloring, headers/footers, case scenario coloring, command-line- dependent definition coloring, and includes over 50 pre- made definition files.
compare is similar to cmp but faster and with better readable output. compare examines one file and standard in, or two files on a byte by byte basis, and prints the file position of the first difference it finds, first in decimal and then in hexadecimal, followed by the differing byte content in hexadecimal and a quoted character.
cz2cz tools is software for converting texts between various charset encodings that are used in the Czech language. The most important feature is autodetection of the most-used encodings (UTF-8, ISO-8859-2, Win-1250, cp850, and Kamenickych). There are both console non-interactive (text-based) and interactive (curses) applications. cz2cz also allows you to convert characters with diacritics to TeX (LaTeX) conventions. The interactive part of cz2cz tools can be used for quick manual complementing of diacritics to texts.
dvipng makes PNG or GIF graphics from DVI files obtained from TeX and its relatives. Its benefits include speed; it uses very fast bitmap-rendering code for DVI files. Furthermore, it does not read the postamble, so it can be started before TeX finishes. It supports PK, VF, PostScript Type1 (via FreeType or t1lib), and TrueType fonts (via FreeType), color specials, can render CJK fonts, and more.
