+For the remainder of the command line arguments, assume that files
+mentioned with @code{-l} and expressions passed with @code{-c} are
+written in @var{lang}.  @var{lang} must be the name of one of the
+languages supported by the compiler (@pxref{Compiler Tower}).  When run
+interactively, set the REPL's language to @var{lang} (@pxref{Using Guile
+Interactively}).
+
+The default language is @code{scheme}; other interesting values include
address@hidden (for Emacs Lisp), and @code{ecmascript}.
+
+The example below shows the evaluation of expressions in Scheme, Emacs
+Lisp, and ECMAScript:
+
address@hidden
+guile -c "(apply + '(1 2))"
+guile --language=elisp -c "(= (funcall (symbol-function '+) 1 2) 3)"

address@hidden file name separator
address@hidden absolute file name
+
+Many operating systems, such as GNU, use @code{/} (forward slash) to
+separate the components of a file name; any file name starting with
address@hidden/} is considered an @dfn{absolute file name}.  These conventions
+are specified by the POSIX Base Definitions, which refer to conforming
+file names as ``pathnames''.  Some operating systems use a different
+convention; in particular, Windows uses @code{\} (backslash) as the file
+name separator, and also has the notion of @dfn{volume names} like
address@hidden:\} for absolute file names.  The following procedures and
+variables provide support for portable file name manipulations.
+
address@hidden {Scheme Procedure} system-file-name-convention
+Return either @code{posix} or @code{windows}, depending on
