+dnl @synopsis AC_LIB_READLINE
+dnl
+dnl Searches for a readline compatible library. If found, defines
+dnl `HAVE_LIBREADLINE'. If the found library has the `add_history'
+dnl function, sets also `HAVE_READLINE_HISTORY'. Also checks for the
+dnl locations of the necessary include files and sets `HAVE_READLINE_H'
+dnl or `HAVE_READLINE_READLINE_H' and `HAVE_READLINE_HISTORY_H' or
+dnl 'HAVE_HISTORY_H' if the corresponding include files exists.
+dnl
+dnl The libraries that may be readline compatible are `libedit',
+dnl `libeditline' and `libreadline'. Sometimes we need to link a termcap
+dnl library for readline to work, this macro tests these cases too by
+dnl trying to link with `libtermcap', `libcurses' or `libncurses' before
+dnl giving up.
+dnl
+dnl Here is an example of how to use the information provided by this
+dnl macro to perform the necessary includes or declarations in a C file:
+dnl
+dnl #include <config.h>
+dnl
+dnl #ifdef HAVE_LIBREADLINE
+dnl #if defined(HAVE_READLINE_READLINE_H)
+dnl #include <readline/readline.h>
+dnl #elif defined(HAVE_READLINE_H)
+dnl #include <readline.h>
+dnl #else /* !defined(HAVE_READLINE_H) */
+dnl extern char *readline ();
+dnl #endif /* !defined(HAVE_READLINE_H) */
+dnl char *cmdline = NULL;
+dnl #else /* !defined(HAVE_READLINE_READLINE_H) */
+dnl /* no readline */
+dnl #endif /* HAVE_LIBREADLINE */
+dnl
+dnl #ifdef HAVE_READLINE_HISTORY
+dnl #if defined(HAVE_READLINE_HISTORY_H)
+dnl #include <readline/history.h>
+dnl #elif defined(HAVE_HISTORY_H)
+dnl #include <history.h>
+dnl #else /* !defined(HAVE_HISTORY_H) */
+dnl extern void add_history ();
+dnl extern int write_history ();
+dnl extern int read_history ();
+dnl #endif /* defined(HAVE_READLINE_HISTORY_H) */
+dnl /* no history */
+dnl #endif /* HAVE_READLINE_HISTORY */
