GNU AutoGen/AutoOpts is a two-part project that serves two separate
purposes.  The two parts are combined because they are inextricably
intertwined:

AutoGen is a tool designed to simplify the creation and maintenance of
programs that contain large amounts of repetitious text.  It is
especially valuable in programs that have several blocks of text that
must be kept synchronized.

AutoOpts is both an example of that and a project in its own right.
It is a very powerful configuration file, environment variable and
command line option documentation and management tool consisting of a
set of AutoGen templates and a run time library that nearly eliminates
the hassle of managing, parsing and documenting program options.

New in 5.14 - December 29, 2011

Here are the 'NEWS' entries since the last release

* getopt support has been improved.  Developers using generated code
   that called that function had to arrange for the autoopts/option.h
   header to be available.  That text is now inserted into the code.

* dependency tracking improvements.  renaming an output file confused
   the code and licensing files were not listed.

* libopts did not provide the full executable path name in pzProgPath
   if it was not supplied in argv[0].  "pathfind(3GEN)" is now used
   in that case.

* makefile-script function will now honor the "then", "else" and "in"
   keywords appearing at the end of a line.  "makefile-script" splices
   lines together with a semi-colon and a backslash, add a leading tab
   to each line and double dollar sign characters, basically turning
   semi-ordinary shell scripts into scripts suitable for use with make.
   In the case of these keywords and certain operators, the semi-colon
   is now omitted.

   Additionally, it produces text that can be post-processed at
   configure time in that it will leave alone any lines starting with
   "@ifdef", "@ifndef", "@else" and "@endif".  See the second argument
   to the AC_CONFIG_FILES() autoconf macro for details.
