+2002-02-25 : Christos Zoulas <christos@netbsd.org>
+	* Bring in constification fixes from NetBSD tree.
+	* Use NetBSD's vis, fgetln
+
+2002-02-10 : Jason Evans <jasone@freebsd.org>
+
+	* Makefile.in : Append "" arguments to for loops, to avoid syntax errors
+          with some shells that occur if there are no arguments to the for
+          loops.
+
+2002-02-09 : Jason Evans <jasone@freebsd.org>
+
+	* Install man pages in @prefix@/man/, rather than @prefix@/share/man.
+
+	* Fix the Darwin -install_name S_LDFLAGS argument to default to a prefix
+          of /usr/local if --prefix is not specified.
+
+2002-02-05 : Jason Evans <jasone@freebsd.org>
+
+	* Convert to using an autoconf-generated config.h, rather than passing
+	  -D_HAVE_<foo>=1 definitions on the command line.  Include sys.h in
+	  config.h, and include config.h in .c files rather than sys.h.
+
+	* Mangle function names for implementations in the np directory in order
+          to avoid namespace collisions with other code that may provide copies
+          of the same unimplemented functions.  For example:
+
+		#define	fgetln libedit_fgetln
+
+2002-02-03 : Jason Evans <jasone@freebsd.org>
+
+	* Add autoconf infrastructure, plus a generic Makefile that works with
+          at least BSD make, GNU make and Sun make.
+
+	* Port and/or test on FreeBSD 4.5, FreeBSD-current, NetBSD 1.5 (sparc64
+          and arm32), Apple OS X 10.1.2, Solaris 2.6, and Red Hat Linux 2.6.
+          Add the np directory, which contains implementations of non-portable
+          functions.
+
+	* Add the LIBEDIT_MAJOR and LIBEDIT_MINOR macros to histedit.h, since
+          there is otherwise no straightforward method of programmatically
+          detecting the library version.

+Building this distribution in many cases is as simple as typing the following
+while in the root directory of the source tree:
+
+	./configure
+	make
+
+To install, do the above, then type:
+
+	make install
+
+Additional build targets of finer granularity include:
+
+	lib_a
+	lib_s
+	install_hdr
+	install_lib
+	install_lib_a
+	install_lib_s
+	install_man
+	test
+
+Cleanup targets include:
+
+	clean
+	distclean
+
+Optionally, pass any of the following (not a definitive list) arguments to
+'configure':
+
+--prefix=<install-root-dir>
+	Set the base directory in which to install.  For example:
+	
+		./configure --prefix=/usr/local
+
+	will cause files to be installed into /usr/local/bin, /usr/local/man,
+	/usr/local/include, /usr/local/lib, and /usr/local/share.
+
+--disable-readline
+	By default, libedit is built and installed such that it works as a
+	drop-in replacement for the readline library.  This option turns that
+	behavior off.
+
+--enable-debug
+	Build debugging code (for libedit development).
+
+Optionally, define environment variables, including (not exclusively):
+
+CFLAGS="?"
+	Pass these flags to the compiler.  You probably shouldn't define this
+	unless you know what you are doing.
+
+CPPFLAGS="?"
+	Pass these flags to the C preprocessor.  Note that CFLAGS is not passed
+	to 'cpp' when 'configure' is looking for include files, so you must use 
+	CPPFLAGS instead if you need to help 'configure' find header files.
+
+LD_LIBRARY_PATH="?"
+	'ld' uses this colon-separated list to find libraries.
+
+LDFLAGS="?"
+	Flags passed to 'gcc', which should normally be passed on to 'ld'.
+
+PATH="?"
+	'configure' uses this to find programs.

+.Sh DESCRIPTION
+The
+.Nm
+library provides generic line editing and history functions,
+similar to those found in
+.Xr sh 1 .
+.Pp
+These functions are available in the
+.Nm libedit
+library (which needs the
+.Nm libtermcap
+library).
+Programs should be linked with
+.Fl ledit ltermcap .
+.Sh LINE EDITING FUNCTIONS
+The line editing functions use a common data structure,
+.Fa EditLine ,
+which is created by
+.Fn el_init
+and freed by
+.Fn el_end .
+.Pp
+The following functions are available:
+.Bl -tag -width 4n
+.It Fn el_init
+Initialise the line editor, and return a data structure
+to be used by all other line editing functions.
+.Fa prog
+is the name of the invoking program, used when reading the
+.Xr editrc 5
+file to determine which settings to use.
+.Fa fin ,
+.Fa fout
+and
+.Fa ferr
+are the input, output, and error streams (respectively) to use.
+In this documentation, references to
+.Dq the tty
+are actually to this input/output stream combination.
+.It Fn el_end
+Clean up and finish with
+.Fa e ,
+assumed to have been created with
+.Fn el_init .
+.It Fn el_reset
+Reset the tty and the parser.
+This should be called after an error which may have upset the tty's
+state.
+.It Fn el_gets
+Read a line from the tty.
+.Fa count
+is modified to contain the number of characters read.
+Returns the line read if successful, or
+.Dv NULL
+if no characters were read or if an error occurred.
+.It Fn el_getc
+Read a character from the tty.
+.Fa ch
+is modified to contain the character read.
+Returns the number of characters read if successful, -1 otherwise.
+.It Fn el_push
+Pushes
+.Fa str
+back onto the input stream.
+This is used by the macro expansion mechanism.
+Refer to the description of
+.Ic bind
+.Fl s
+in
+.Xr editrc 5
+for more information.
+.It Fn el_parse
+Parses the
+.Fa argv
+array (which is
+.Fa argc
+elements in size)
+to execute builtin
+.Nm
+commands.
+If the command is prefixed with
+.Dq prog :
+then
+.Fn el_parse
+will only execute the command if
+.Dq prog
+matches the
+.Fa prog
+argument supplied to
+.Fn el_init .
+The return value is
+-1 if the command is unknown,
+0 if there was no error or
+.Dq prog
+didn't match, or
+1 if the command returned an error.
+Refer to
+.Xr editrc 5
+for more information.
+.It Fn el_set
+Set
+.Nm
+parameters.
+.Fa op
+determines which parameter to set, and each operation has its
+own parameter list.

+.It Dv EL_HIST , Xo
+.Fa "History *(*func)(History *, int op, ...)" ,
+.Fa "const char *ptr"
+.Xc
+Defines which history function to use, which is usually
+.Fn history .
+.Fa ptr
+should be the value returned by
+.Fn history_init .
+.It Dv EL_EDITMODE , Fa "int flag"
+If
+.Fa flag
+is non-zero,
+editing is enabled (the default).
+Note that this is only an indication, and does not
+affect the operation of
+.Nm "" .
+At this time, it is the caller's responsibility to
+check this
+(using
+.Fn el_get )
+to determine if editing should be enabled or not.
+.It Dv EL_GETCFN , Fa "int (*f)(EditLine *, char *c)"
+Define the character reading function as
+.Fa f ,
+which is to return the number of characters read and store them in
+.Fa c .
+This function is called internally by
+.Fn el_gets
+and
+.Fn el_getc .
+The builtin function can be set or restored with the special function
+name ``EL_BUILTIN_GETCFN''.
+.It Dv EL_CLIENTDATA , Fa "void *data"

+.Sh NAME
+.Nm editrc
+.Nd configuration file for editline library
+.Sh SYNOPSIS
+.Nm
+.Sh DESCRIPTION
+The
+.Nm
+file defines various settings to be used by the
+.Xr editline 3
+library.
+.Pp
+The format of each line is:
+.Dl [prog:]command [arg [...]]
+.Pp
+.Ar command
+is one of the
+.Xr editline 3
+builtin commands.
+Refer to
+.Sx BUILTIN COMMANDS
+for more information.
+.Pp
+.Ar prog
+is the program name string that a program defines when it calls
+.Xr el_init 3
+to setup
+.Xr editline 3 ,
+which is usually
+.Va argv[0] .
+.Ar command
+will be executed for any program which matches
+.Ar prog .
+.Pp
+.Ar prog
+may also be a
+.Xr regex 3
+style
+regular expression, in which case
+.Ar command
+will be executed for any program that matches the regular expression.
+.Pp
+If
+.Ar prog
+is absent,
+.Ar command
+is executed for all programs.
+.Sh BUILTIN COMMANDS
+The
+.Nm editline
+library has some builtin commands, which affect the way
+that the line editing and history functions operate.
+These are based on similar named builtins present in the
+.Xr tcsh 1
+shell.
+.Pp
+The following builtin commands are available:
+.Bl -tag -width 4n
+.It Ic bind Xo
+.Op Fl a
+.Op Fl e
+.Op Fl k
+.Op Fl l
+.Op Fl r
+.Op Fl s
+.Op Fl v
+.Op Ar key Op Ar command
+.Xc
+Without options, list all bound keys, and the editor command to which
+each is bound.
+If
+.Ar key
+is supplied, show the bindings for
+.Ar key .
+If
+.Ar key command
+is supplied, bind
+.Ar command
+to
+.Ar key .
+Options include:
+.Bl -tag -width 4n
+.It Fl e
+Bind all keys to the standard GNU Emacs-like bindings.
+.It Fl v
+Bind all keys to the standard
+.Xr vi 1 -like
+bindings.
+.It Fl a
+List or change key bindings in the
+.Xr vi 1
+mode alternate (command mode) key map.
+.It Fl k
+.Ar key
+is interpreted as a symbolic arrow key name, which may be one of
+.Sq up ,
+.Sq down ,
+.Sq left
+or
+.Sq right .
+.It Fl l
+List all editor commands and a short description of each.
+.It Fl r
+Remove a key's binding.
+.It Fl s
+.Ar command
+is taken as a literal string and treated as terminal input when
+.Ar key
+is typed.
+Bound keys in
+.Ar command
+are themselves reinterpreted, and this continues for ten levels of
+interpretation.
+.El
+.Pp
+.Ar command
+may be one of the commands documented in
+.Sx "EDITOR COMMANDS"
+below, or another key.
+.Pp
+.Ar key
+and
+.Ar command
+can contain control characters of the form
+.Sm off
+.Sq No ^ Ar character
+.Sm on
+.Po
+e.g.
+.Sq ^A
+.Pc ,
+and the following backslashed escape sequences:
+.Pp
+.Bl -tag -compact -offset indent -width 4n

+Backspace
+.It Ic \ee
+Escape
+.It Ic \ef
+Formfeed
+.It Ic \en
+Newline
+.It Ic \er
+Carriage return
+.It Ic \et
+Horizontal tab
+.It Ic \ev
+Vertical tab
+.Sm off
+.It Sy \e Ar nnn
+.Sm on
+The ASCII character corresponding to the octal number
+.Ar nnn .
+.El
+.Pp
+.Sq \e
+nullifies the special meaning of the following character,
+if it has any, notably
+.Sq \e
+and
+.Sq ^ .
+.It Ic echotc Xo
+.Op Fl sv
+.Ar arg
+.Ar ...
+.Xc
+Exercise terminal capabilities given in
+.Ar arg Ar ... .
+If
+.Ar arg
+is
+.Sq baud ,
+.Sq cols ,
+.Sq lines ,
+.Sq rows ,
+.Sq meta or
+.Sq tabs ,
+the value of that capability is printed, with
+.Dq yes
+or
+.Dq no
+indicating that the terminal does or does not have that capability.
+.Pp
+.Fl s
+returns an emptry string for non-existent capabilities, rather than
+causing an error.
+.Fl v
+causes messages to be verbose.
+.It Ic edit Op Li on | Li off
+Enable or disable the
+.Nm editline
+functionality in a program.
+.It Ic history
+List the history.
+.It Ic telltc
+List the values of all the terminal capabilities (see
+.Xr termcap 5 ) .
+.It Ic settc Ar cap Ar val
+Set the terminal capability
+.Ar cap
+to
+.Ar val ,
+as defined in
+.Xr termcap 5 .
+No sanity checking is done.
+.It Ic setty Xo
+.Op Fl a
+.Op Fl d
+.Op Fl q
+.Op Fl x
+.Op Ar +mode
+.Op Ar -mode
+.Op Ar mode
+.Xc
+Control which tty modes that

+won't allow the user to change.
+.Fl d ,
+.Fl q
+or
+.Fl x
+tells
+.Ic setty
+to act on the
+.Sq edit ,
+.Sq quote
+or
+.Sq execute
+set of tty modes respectively; defaulting to
+.Fl x .
+.Pp
+Without other arguments,
+.Ic setty
+lists the modes in the chosen set which are fixed on
+.Po
+.Sq +mode
+.Pc
+or off
+.Po
+.Sq -mode
+.Pc .
+.Fl a
+lists all tty modes in the chosen set regardless of the setting.
+With
