- **/
+ *
+ * GLib provides the functions g_shell_quote() and g_shell_unquote()
+ * to handle shell-like quoting in strings. The function g_shell_parse_argv()
+ * parses a string similar to the way a POSIX shell (/bin/sh) would.
+ *
+ * Note that string handling in shells has many obscure and historical
+ * corner-cases which these functions do not necessarily reproduce. They
+ * are good enough in practice, though.
