ECB is a source code browser for (x)emacs. It
displays a couple of windows that can be used to
browse directories, files, and file contents like
methods and variables. It supports source code
parsing for languages like Java, C, C++, Elisp,
Scheme, Perl, TeX, LaTeX, etc. In addition, it
offers an (optional) permanent "compile window" at
the bottom of the emacs frame, which is used to
display all help and compile output. The rest of
the frame is called the "edit area", which can be
divided into several edit windows that are used
for editing the sources. Deleting some of the edit
windows neither destroys the compile window nor
the browsing windows. It requires the CEDET suite.
