    (description
     "Ragel compiles executable finite state machines from regular languages.
Ragel targets C, C++, Obj-C, C#, D, Java, Go and Ruby.  Ragel state machines
can not only recognize byte sequences as regular expression machines do, but
can also execute code at arbitrary points in the recognition of a regular
language.  Code embedding is done using inline operators that do not disrupt
the regular language syntax.")

profile, which needlessly clutters the output.  It also prevents Geiser (if
installed) from blocking the script and asking the user to input the Scheme
implementation to use.

The trick for passing multiple arguments to Emacs is to use what is called a
"sesquicolon" (see https://www.emacswiki.org/emacs/EmacsScripts).

* etc/indent-code.el.in: Rename to...
* etc/indent-code.el: ...this.  Adapt the shebang to use a sesquicolon, and
pass the --quick option to Emacs.  Since this line is interpreted by the
shell, simply use Emacs from the PATH instead of from a hard coded location.
(main): New procedure, used as the entry point.
* configure.ac: Remove the warning about Emacs.  Emacs can now be installed
any time by the user if they want to use the script.
* .gitignore: No longer ignore changes to etc/indent-code.el.
