I maintain a number of elisp packages (e.g. codesearch, emacs-ycmd, traad) that would benefit from being able to install the external programs that they use, saving time and effort for some users. For example, with codesearch.el it would be nice to…

I have a package for interacting with GRASS GIS processes, available on MELPA. The rate of development and number of users are both quite low, so there's no need for a mailing list or any formal communications with my users.

How to generate and activate autoloads for local packages?
It is clear that not all local/custom/personal packages should be officially released, and it would be silly to do so just to benefit from built-in package management support. I'm wondering how to generate and activate autoloads for local packages?…

Manually installing a multifile package to “elpa/”
When I'm writing a new package, it's great that I can test its
installation by just issuing M-x package-install-from-buffer. This
will install the package with package.el, so that it goes under
