-@cindex purpose\n\
-\n\
-The %s @command{foo} program serves as a minimal example of a %s utility.\n\
-Its purpose is to show how to build and document small command-line tools\n\
-that follow GNU-style conventions.\n\
-\n\
-@itemize @bullet\n\
-@item\n\
-Implements clean command-line option parsing using GNU-style long options.\n\
-@item\n\
-Provides simple, predictable behavior for testing build systems.\n\
-@item\n\
-Demonstrates how to write Texinfo manuals for %s programs.\n\
-@end itemize\n\
-\n\
-@cindex implementation\n\
-%s foo is implemented in C and follows the GNU coding and maintainer standards.\n\
-It uses Autotools for configuration and build setup, and Texinfo for documentation.\n\
-\n\
-\n\
-@node Sample output\n\
-@chapter Sample output\n\
-\n\
-@cindex examples\n\
-@cindex sample output\n\
-\n\
-Here are some examples of running %s foo:\n\
-\n\
-@example\n\
-$ foo\n\
-foo: hello, world!\n\
-@end example\n\
-\n\
-@example\n\
-$ foo --message=\"%s rules!\"\n\
-foo: %s rules!\n\
-@end example\n\
-\n\

-$ foo --version\n\
-%s foo @value{VERSION}\n\

-@node Invoking foo\n\
-@chapter Invoking @command{foo}\n\
-\n\
-@cindex invoking\n\
-@cindex usage\n\
-@cindex options\n\
-\n\
-The general form for running @command{foo} is:\n\
-\n\
-@example\n\
-foo @var{option} @dots{}\n\
-@end example\n\
-\n\
-With no options, @command{foo} prints a default message.\n\
-\n\
-@command{foo} supports the following options:\n\
-\n\
-@table @option\n\
-@item --message=@var{text}\n\
-@itemx -m @var{text}\n\
-@opindex --message\n\
-@opindex -m\n\
-Print @var{text} instead of the default greeting.\n\
-\n\
-@item --help\n\
-@itemx -h\n\
-@opindex --help\n\
-@opindex -h\n\
-Display help text and exit successfully.\n\
-\n\
-@item --version\n\
-@itemx -v\n\
-@opindex --version\n\
-@opindex -v\n\
-Print the version number and licensing information, then exit.\n\

-Bug reports:\n\
- Please include enough information for the maintainers to reproduce the\n\
- problem. Generally speaking, that means:\n\
-- the contents of any input files necessary to reproduce the bug\n\
-  and command line invocations of the program(s) involved (crucial!).\n\
-- a description of the problem and any samples of the erroneous output.\n\
-- the version number of the program(s) involved (use --version).\n\
-- hardware, operating system, and compiler versions (uname -a).\n\
-- unusual options you gave to configure, if any (see config.mak).\n\
-- anything else that you think would be helpful.\n\
-\n\
-See README-dev for information on the development environment -- any\n\
-interested parties are welcome. If you're a programmer and wish to\n\
-contribute, this should get you started. If you're not a programmer,\n\
-your help in writing test cases, checking documentation against the\n\
-implementation, etc., would still be very much appreciated.\n\

-\n\
-Basic Installation\n\
-==================\n\
-\n\
-   Briefly, the shell command `./configure && make && make install` should\n\
-configure, build, and install this package. The following more-detailed\n\
-instruction are generic; see the `README` file for instructions specific to\n\
-this package.\n\
-\n\
-   The `configure` shell script attempts to guess correct values for\n\
-various system-dependent variables used during compilation. It uses\n\
-those values within a `Makefile` to build for that POSIX system as\n\
-defined by `config.mak` which was generated by `configure`.\n\
-\n\
-Compilers and Options\n\
-=====================\n\
-\n\
-  Some systems require unusal options for compilation or linking that\n\
-the `configure` script does not know about. If you run into an issue\n\
-run `./configure --help` to figure out what you can do to fix the\n\
-behavoir.\n\
-\n\
-Installation Names\n\
-==================\n\
-\n\
-  By default, `make install` installs the package's command under\n\
-`/usr/local/bin`. You can specify an installation prefix other than `/usr/local/`\n\
-by giving `configure` the option `--prefix=PREFIX` to `configure`, the package uses\n\
-PREFIX as the prefix for installation programs and libraries.\n\
-Documentation and other data files still use the regular prefix.\n\
-\n\
-`configure` Invokation\n\
-======================\n\
-\n\
-  `configure` recongizes the following options to control its operations.\n\
-\n\
-  `--help`\n\
-     Prints a summary of all the options to `configure`, and exits.\n\
-  `--prefix=PREFIX`\n\
-     Sets the installation prefix.\n\
-  `CFLAGS`\n\
-    Sets the flags used during compilation.\n\
-\n\
-`configure` also accepts some other options. Run `configure --help` for more\n\
