Patches push as 6fcaf8533792a64bc00292326f960561de591200 and following
with some modifications:
 - removed article and period in synopsis
 - added a full sentence at the beginning of the description
 - moved cl-yxorp-cli from "web.scm" to "lisp-xyz.scm" because I got
   an undefined variable error for 'sbcl-yxorp' (I think this is because
   the mutual dependency between "web.scm" and "lisp-xyz.scm" prevents
   using '(inherit sbcl-yxorp)' in this case).
 - replaced '--disable-debugger' by '--non-interactive' in the command
   line for SBCL to be sure that we can't get stuck in SBCL

To find some of the "styling mistakes", you can use:
  ./pre-inst-env guix lint sbcl-yxorp
