Feature/melpa

Hi,

I would like to merge these two changes into APEL. The first is a package description, to be used when building a package (via MELPA). The second is a fix for the issue described here:

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=166226

which occurs when byte-compiling `pces-20.el` when the current directory is read-only.

I tested the function `insert-file-contents-literally` on emacs >= 23 and it works fine, so I don't think we need this check on modern emacs.
