BCAST Implementation for NS2

  empty lines. On empty lines they now act like up-history and
  down-history respectively, as in emacs mode.

  When creating shared libraries under Linux, the -soname directive
  was being used incorrectly. The result is that Linux binaries linked
  with the 1.2.3, 1.2.4 and 1.3.0 versions of the tecla shared
  libraries, will refuse to see other versions of the shared library
  until relinked with version 1.3.1 or higher.

  The configure script can now handle the fact that under Solaris-2.6
  and earlier, the only curses library is a static one that hides in
  /usr/ccs/lib. Under Linux it now also caters for old versions of GNU
  ld which don't accept version scripts.

  The demos are now linked against the shared version of the library
  if possible. Previously they were always linked with the static
  version.

Version 1.3.0:

  The major change in this release is the addition of an optional vi
  command-line editing mode in gl_get_line(), along with lots of new
  action functions to support its bindings. To enable this, first
  create a ~/.teclarc file if you don't already have one, then add the
  following line to it.

   edit-mode vi

  The default vi bindings, which are designed to mimic those of the vi
  editor as closely as possible, are described in the gl_get_line(3)
  man page.

  A new convenience function called ef_list_expansions() has been
  added for listing filename expansions. See the ef_list_expansions(3)
  man page for details. This is used in a new list-glob binding, bound
  to ^Xg in emacs mode, and ^G in vi input mode.

  A bug has been fixed in the key-binding table expansion code. This
  bug would have caused problems to anybody who defined more than
  about 18 personalized key-bindings in their ~/.teclarc file.

Version 1.2.4:

  Buffered I/O is now used for writing to terminals, and where
  supported, cursor motion is done with move-n-positions terminfo
  capabilities instead of doing lots of move-1-position requests. This
  greatly improves how the library feels over slow links.

  You can now optionally compile different architectures in different
  directories, without having to make multiple copies of the
  distribution. This is documented in the INSTALL file.

  The ksh ~+ directive is now supported.

  Thanks to Markus Gyger for the above improvements.

  Documentation has been added to the INSTALL file describing features
  designed to facilitate configuration and installation of the library
  as part of larger packages. These features are intended to remove
  the need to modify the tecla distribution's configuration and build
  procedures when embedding the libtecla distribution in other package
  distributions.

  A previous fix to stop the cursor from warping when the last
  character of the input line was in the last column of the terminal,
  was only being used for the first terminal line of the input line.
  It is now used for all subsequent lines as well, as originally
  intended.
  
Version 1.2.3:

  The installation procedure has been better automated with the
  addition of an autoconf configure script. This means that installers
  can now compile and install the library by typing:

    ./configure
    make
    make install

  On all systems this makes at least the normal static version of the
  tecla library. It also makes the reentrant version if reentrant
  POSIX functions are detected.  Under Solaris, Linux and HP-UX the
  configuration script arranges for shared libraries to be compiled in
  addition to the static libraries.  It is hoped that installers will
  return information about how to compile shared libraries on other
  systems, for inclusion in future releases, and to this end, a new
  PORTING guide has been provided.

  The versioning number scheme has been changed. This release would
  have been 1.2c, but instead will be refered to as 1.2.3. The
  versioning scheme, based on conventions used by Sun Microsystems, is
  described in configure.in.

  The library was also tested under HP-UX, and this revealed two
  serious bugs, both of which have now been fixed.
  
  The first bug prevented the library from writing control codes to
  terminals on big-endian machines, with the exception of those
  running under Solaris. This was due to an int variable being used
  where a char was needed.

  The second bug had the symptom that on systems that don't use the
  newline character as the control code for moving the cursor down a
  line, a newline wasn't started when the user hit enter.

Version 1.2b:

  Two more minor bug fixes:

  Many terminals don't wrap the cursor to the next line when a
  character is written to the rightmost terminal column. Instead, they
  delay starting a new line until one more character is written, at
  which point they move the cursor two positions.  gl_get_line()
  wasn't aware of this, so cursor repositionings just after writing
  the last character of a column, caused it to erroneously go up a
  line. This has now been remedied, using a method that should work
  regardless of whether a terminal exhibits this behavior or not.

  Some systems dynamically record the current terminal dimensions in
  environment variables called LINES and COLUMNS. On such systems,
  during the initial terminal setup, these values should override the
  static values read from the terminal information databases, and now
  do.  Previously they were only used if the dimensions returned by
  terminfo/termcap looked bogus.

Version 1.2a:

  This minor release fixes the following two bugs:

  The initial terminal size and subsequent changes thereto, weren't
  being noticed by gl_get_line(). This was because the test for the
  existence of TIOCWINSZ was erroneously placed before the inclusion
  of termios.h. One of the results was that on input lines that
  spanned more than one terminal line, the cursor occasionally jumped
  unexpectedly to the previous terminal line.

  On entering a line that wrapped over multiple terminal lines,
  gl_get_line() simply output a carriage-return line-feed at the point
  at which the user pressed return. Thus if one typed in such a line,
  then moved back onto one of the earlier terminal lines before
  hitting return, the cursor was left on a line containing part of the
  line that had just been entered. This didn't do any harm, but it
  looked a mess.

Version 1.2:

  A new facility for looking up and completing filenames in UNIX-style
  paths has now been added (eg. you can search for, or complete
  commands using the UNIX PATH environment variable). See the
  pca_lookup_file(3) man page.

  The already existing filename completion callback can now be made
  selective in what types of files it lists. See the
  cpl_complete_word(3) man page.

  Due to its potential to break applications when changed, the use of
  the publically defined CplFileArgs structure to configure the
  cpl_file_completions() callback is now deprecated.  The definition
  of this structure has been frozen, and its documentation has been
  removed from the man pages.  It will remain supported, but if you
  have used it, you are recommended to switch to the new method, which
  involves a new opaque configuration object, allocated via a provided
  constructor function, configured via accessor functions, and
  eventually deleted with a provided destructor function. The
  cpl_file_completions() callback distinguishes which structure type
  it has been sent by virtue of a code placed at the start of the new
  structure by the constructor.  It is assumed that no existing
  applications set the boolean 'escaped' member of the CplFileArgs
  structure to 4568.  The new method is documented in the
  cpl_complete_word(3) man page.
