The current maintainer is Juan Jose Garcia Ripoll.

All CL implementation is compatible with emacs, in the sense that you
can use emacs to edit CL programs, and you can run it with M-x
inferior-lisp RET, or even for most of them (including ecl) with M-x
slime RET.

Almost all projects written by programmers using emacs will contain some
emacs lisp file containing some utility emacs commands the authors use
to edit the project files.

The ecl subdirectory named "src" contains:

[pjb@triton :0 src]$ ls
./           aclocal.m4   clx/             config.sub*   gc/          lsp/
../          bare.lsp.in  cmp/             configure*    gmp/         new-cmp/
CHANGELOG*   c/           compile.lsp.in*  configure.in  h/           util/
Makefile.in  clos/        config.guess*    doc/          install.sh*

I would say cmp/ and new-cmp/ contain compilers.
The c/ contains some C sources, including a file named "interpreter.d".


Concerning personalities, I would say yours doesn't bode well, given
that you didn't fetch the sources and see that yourself.  One wonders
about your motivations...  ;-)
