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