+ Pygments
+ ~~~~~~~~
+
+ Pygments is a syntax highlighting package written in Python.
+
+ It is a generic syntax highlighter for general use in all kinds of software
+ such as forum systems, wikis or other applications that need to prettify
+ source code. Highlights are:
+
+ * a wide range of common languages and markup formats is supported
+ * special attention is paid to details, increasing quality by a fair amount
+ * support for new languages and formats are added easily
+ * a number of output formats, presently HTML, LaTeX, RTF, SVG, all image
+ formats that PIL supports, and ANSI sequences
+ * it is usable as a command-line tool and as a library
+ * ... and it highlights even Brainfuck!
+
+ The `Pygments master branch`_ is installable with ``easy_install Pygments==dev``.
+
+ .. _Pygments master branch:
+ https:/pygments/pygments/archive/master.zip#egg=Pygments-dev
