[slime] swank-loader could use ASDF (#65)

[Daniel Herring]

Hi all,

For what little they're worth, here are my votes on the topic.

Q: Have Quicklisp distribute Slime?
A: Sure!  (Doesn't it already?)

Q: Have Slime rely on ASDF?
A: Sure.  The current Slime loader is generally reliable, but there is 
something to be said for pooling effort in a common solution, and ASDF has 
really improved in recent years.

Q: Have Slime rely on Quicklisp?
A: No way!  You've got this all backwards.  Quicklisp adds downloading, 
dependency management, and such to ASDF.  It also assumes a network 
connection and a certain level of trust in the repository.

Q: Have Slime rely on make?
A: ?!??  GNU Make maybe, but it is essentially a non-starter on MSWin, 
Android, iOS, ....


Thinking about an ideal, non-Quicklisp-assisted install, could something 
like the following work?

- download and extract Slime (zip, tar.gz, or txz)
- open slime-install.lisp in Emacs
- follow some instructions that start an interactive session that 
configures and installs (or upgrades) Slime


Later,
Daniel
