Release v2.14.0.13

We apologize for the calc v2.14.0.12 source tarball that was missing
critical files.  While the executable was well tested, our release
process was deficient.

We are improved our release process and added tests during the release
procedure to help verify that we are not regressing in to the
"v2.14.0.12 source tarball" issue, among other things.

Depending on how things do, you might is several releases come out over
a short period of time.  The core of calc isn't changing, so the calc
executable will be the same as we focus on the Makefiles, our release
procedure, and related documentation / help files.

Removed constructed help file that incorrectly added as a src file.

The following are the changes in this release:

    Made major changes to our release process in order to avoid
    missing critical files that happened in calc v2.4.0.12.

    Minor tweak to seed() builtin.  Updated help/srand and help/srandom.

    Moved Makefile.ship into Makefile.

    Removed custom/Makefile.head and custom/Makefile.tail.

    The custom/Makefile is now part of source and includes Makefile.
    In particular, custom/Makefile makes use of the 'middle' of
    the new top level Makefile where calc's top level Makefile
    variables are defined.

    Makefile.simple and custom/Makefile.simple are now part of the source
    and are constructed from Makefile and custom/Makefile respectively.
    The Makefile.simple and custom/Makefile.simple avoid using GNU
    conditionals. They may be used with older/classic make commands.

    Makefile.local will include comments about how to better use
    it. Between releases, Makefile.local at the top of the master branch
    will contain how we typically build calc and test calc (FYI: we
    normally enable things such as -Werror -Wextra -pedantic).  When we
    push out a release, Makefile.local will be stripped of non-comment
    lines.  Thus, releases of calc, and, released "calc*.src.rpm"
    files and the source tarballs, will have a Makefile.local with
    only comments.

    The "README.*" files and "HOWTO.INSTALL" file have been updated.

    By default, compiler warnings have been turned up.  The Makefile
    variable ${CCWARN} now defaults to:

	CCWARN= -Wall -Wextra -pedantic

    The previous level of compiler warnings can be easily restored by
    adding to Makefile.local:

	CCWARN:= -Wall

    The readline, history and ncurses libraries are now default.
    The Makefile variables ${USE_READLINE}, ${READLINE_LIB}, and
    ${READLINE_EXTRAS} now default to:

	USE_READLINE= -DUSE_READLINE
	READLINE_LIB= -lreadline
	READLINE_EXTRAS= -lhistory -lncurses

    The previous mode where readline, history and ncurses libraries
    were not compiled in by default can be easily restored by
    adding to Makefile.local:

	USE_READLINE:=
	READLINE_LIB:=
	READLINE_EXTRAS:=

    We have renamed "stable" as "production".
    We have renamed "unstable" as "tested".

    On the web site:

	http://www.isthe.com/chongo/src/calc/

    these files has been renamed:

	2.x.y.z_IS_LATEST_STABLE   ==> 2.x.y.z_IS_LATEST_PRODUCTION
	2.x.y.z_IS_LATEST_UNSTABLE ==> 2.x.y.z_IS_LATEST_TESTED

    The terms 'stable' and 'unstable' were both misleading and
    inaccurate.  For details see the new documention file:

	README.RELEASE

    See also the help command:

	; help release

    Fixed bug impacting how have_ustat.h was formed.

    Updated help/archive, BUGS, HOWTO.INSTALL to reflect GitHub use.
