Enhanced Carbon Emacs is now a universal enhancement plugin for arbitrary (Unix, Carbon, or Aqua) Emacs distributions (such as Yaced, Aquamacs, CarbonEmacs Tiger, or the native Darwin Emacs in /usr/bin/Emacs). This includes a fully customisable LaTeX editing environment based on AucTeX, RefTeX, Preview and other packages.
Basically, ECE is a convenient way to properly install a large number of pre-configured useful packages for LaTeX users, which includes a hack of AUCTeX, that allows to have a more intuitive handling of the "view" command in a macintosh context (in particular, for non-PDFtex users willing to preview in PDF), and to use simpdftex and DVIPDFMx in a seamless way. From Emacs, you can launch directly any LaTeX process or any Mac application on files or regions you are working on.
