+
+;; "Shell quasiquote" -- turn s-expressions into shell command strings.
+;;
+;; Quoting is automatic for POSIX shells.
+;;
+;;   (let ((file1 "file one")
+;;         (file2 "file two"))
+;;     (shqq (cp -r ,file1 ,file2 "My Files")))
+;;       => "cp -r 'file one' 'file two' 'My Files'"
+;;
+;; You can splice many arguments into place with ,@foo.
+;;
+;;   (let ((files (list "file one" "file two")))
+;;     (shqq (cp -r ,@files "My Files")))
+;;       => "cp -r 'file one' 'file two' 'My Files'"
+;;
+;; Note that the quoting disables a variety of shell expansions like ~/foo,
+;; $ENV_VAR, and e.g. {x..y} in GNU Bash.
+;;
+;; You can use ,,foo to escape the quoting.
+;;
+;;   (let ((files "file1 file2"))
+;;     (shqq (cp -r ,,files "My Files")))
+;;       => "cp -r file1 file2 'My Files'"
+;;
+;; And ,,@foo to splice and escape quoting.
+;;
+;;   (let* ((arglist '("-x 'foo bar' -y baz"))
+;;          (arglist (append arglist '("-z 'qux fux'"))))
+;;     (shqq (command ,,@arglist)))
+;;       => "command -x 'foo bar' -y baz -z 'qux fux'"
