The following two patches add rx (a dependency of scsh) and scsh.

For what my limited testing shows, it works.

+Well, unix shells are powerful tools.  They allow a user to concisely specify
+her commands and the communications between them (piping, redirecting, &c.).
+When she needs to do something more complex than running a set of commands
+with known inputs, however, things become complicated.  General programming
+with sh can be unpleasant and error prone, to say the least.
+
+Scheme is a simple, expressive general programming language.  A user with some
+taste may want to use it to wield her computing machine.  For simple commands,
+however, it is not the most concise.  At the scale of the command line, even the
+overhead of parentheses matters.  It would be nice to use each of these languages
+where their strengths lie.
+
+Scsh is the solution.  It allows the user to write commands in a language within
+Scheme that follows the unix way, but also allows her to specify more complex
+commands with the elegance of Scheme.")

I got these to build fine and ran scsh.  Looks good!

Should we probably rename go scheme48-rx and scheme48-scsh for
consistency in how we're packaging other projects?  WDYT?  At least for
scheme48-rx... maybe one could argue that scsh is more standalone,
though I think even that should be scheme48-scsh since maybe guile-scsh
will have a resurgence.

With that change I think it's okay to merge and push these up.

Okay, some tweaks made:

 - Updated the description to be shorter and less opinionated.
 - Renamed rx to scheme48-rx.
 - Switched from copying in rx library to scsh entirely to making it
   a symlink.

With those changes done, pushed!
