AUCTEX is an extensible package for writing and formatting TeX files in GNU Emacs and XEmacs.
It provides the most extensive LaTeX editing support available for a general purpose editor. Apart from the customary TeX shell functionality, it provides syntax highlighting, smart indentation and formatting, previews of mathematics and other stuff right in the editing buffer (preview-latex), smart folding of syntactical elements, macro and environment completion. It also supports the self-documenting .dtx format from the LaTeX project. Support for other TeX-based formats includes ConTeXt and plain TeX, but is quite more sketchy.
AUCTeX was started by students from Aalborg University Center (now Aalborg University), hence the name AUCTeX.
