A related desire of mine is to have both the latest stable release of
an egg and the latest development release installed with *the latest
stable release being the default* (i.e. listed, with all its stable
dependencies, in easy-install.pth). Something along the lines of an -M
option, which like -m, performs a multi-version install but doesn't
touch easy-install.pth. I'm not sure if this is feasible (or maybe it
is even already possible!), but it sounds nice to me. :)
