EasyDTX is a variant of the DTX format which eliminates the need for all those pesky macrocode environments. Any line introduced by a single comment counts as documentation, and documentation lines may be indented. An .edtx file is converted to a .dtx by a Perl script called edtx2dtx. There is also a rudimentary Emacs mode, implemented in easydoctex-mode.el, which takes care of fontification, indentation, and forward and inverse search.
