dnl @synopsis VL_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 #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 */
