## Summary:
This package automates the management of local Lisp code. Similar
to package.el, it will byte-compile files, scrape for autoload
cookies and update the `load-path', but "installing" a package just
involves placing a file or a directory into a "site-lisp"
directory, inside your Emacs configuration directory (see
`site-lisp-directory' if you wish to modify this behaviour).
## Recent NEWS:
* Allow `site-lisp-directory' to be a list of directories.
