Release calc version 2.12.6.2

We part of our experimenting with GitHub, we reset the history
of this repository.

Anyone who was tracking the calc "pre-release" on GitHub prior
to version 2.12.6.0 should do a:

    git reset --hard origin/master
    git cleanup -f

Or you may just want to start over:

    rm -rf calc
    git clone https://github.com/lcn2/calc.git

Sorry about that.  The previous GitHub repository was an useful
experiment.  Based on what we learned, we decided to rebuild it.

+The following are the changes from calc version 2.12.6.1 to date:
+
+    Improved gen_v1(h,n) in lucas.cal to use an even faster search method.
+
+    Improved are checking in lucas.cal.  In particular both h and n must be
+    integers >= 1.  In the case of both rodseth_xhn(x, h, n) and gen_v1(h, n)
+    h must be odd.
+
+    Fixed an C code intending issue that was reported by Thomas Walter
+    <th dot walter42 at gmx dot de> in zfunc.c.
+
+
+The following are the changes from calc version 2.12.6.0 to 2.12.6.0:
+
+    Added the makefile variable ${COMMON_ADD} that will add flags
+    to all compile and link commands. The ${COMMON_ADD} flags are
+    appended to both ${COMMON_CFLAGS} and ${COMMON_LDFLAGS}.  This
+    facility is available to nearly all platforms except those with
+    very old make commands that do not understand the += operator.
+
+    Example on macOS (Darwin), one may invoke clang's -fsanitize
+    facility by:
+
+	make clobber all \
+	  COMMON_ADD='-fsanitize=undefined -fsanitize=address'
+
+    Another example.  To force C warnings to be treated as errors:
+
+	make COMMON_ADD='-Werror'
+
+    Created a GitHub repository for calc:
+
+	https://github.com/lcn2/calc
+
+    NOTE: The calc GitHub repository represents the an active
+	  development stream.  While an effort will be made to keep
+	  the master branch of the calc GitHub repository in working
+	  order, that tree may be unstable.  Those wishing for more
+	  reliable releases use releases found at calc mirror sites:
+
+	    http://www.isthe.com/chongo/tech/comp/calc/calc-mirror.html
+
+    IMPORTANT NOTE:
+
+	On 2017 June 05, the calc GitHub history was re-written.
+	Anyone who was tracking the calc "pre-release" on GitHub prior
+	to version 2.12.6.0 should do a:

+
+    Renamed README to README.FIRST.  Added README.md for the
+    GitHub repository.
+
+    Fixed reading from standard input (stdin) when -p is given on
+    the command line.  This now prints hello:
+
+	echo hello | calc -p 'stdin = files(0); print fgetline(stdin);'
+
+    Added more debugging related to stdin when bit 4 of calc_debug
+    is set (e.g., running calc with -D16).
+
+    Updated the calc(1) man page and 'help file' to explain about
+    reading from standard input (stdin).
+
+    Added some clarifying remarks for 'help ptest' explaining that
+    the ptest builtin can return 1 is some cases where the test
+    value is a pseudoprime.
+
+    Removed duplicate copyright comments from the help/builtin that
+    is built.

+# What is calc?
+
+Calc is an interactive calculator which provides for easy large
+Otherwise, it enters interactive mode.  In this mode, it accepts
+commands one at a time, processes them, and displays the answers.
+In the simplest case, commands are simply expressions which are
+evaluated.  For example, the following line can be input:
+
+```sh
+3 * (4 + 1)
+```
+
+and the calculator will print:
+
+```sh
+15
+```
+
+Calc as the usual collection of arithmetic operators +, -, /, * as
+well as ^ (exponentiation), % (modulus) and // (integer divide).
+For example:
+
+```sh
+3 * 19^43 - 1
+```
+
+will produce:
+
+```sh
+29075426613099201338473141505176993450849249622191102976
+```
+
+Notice that calc values can be very large.  For example:
+
+```sh
+2^23209-1
+```
+
+will print:
+
+```sh
+402874115778988778181873329071 ... many digits ... 3779264511
+```
+
+The special '.' symbol (called dot), represents the result of the
+last command expression, if any.  This is of great use when a series
+of partial results are calculated, or when the output mode is changed
+and the last result needs to be redisplayed.  For example, the above
+result can be modified by typing:
+
+```sh
+. % (2^127-1)
+```
+
+and the calculator will print:
+
+```sh
+47385033654019111249345128555354223304
+```
+
+For more complex calculations, variables can be used to save the
+intermediate results.  For example, the result of adding 7 to the
+previous result can be saved by typing:
+
+```sh
+curds = 15
+whey = 7 + 2*curds
+```
+
+Functions can be used in expressions.  There are a great number of
+pre-defined functions.  For example, the following will calculate
+the factorial of the value of 'whey':
+
+```sh
+fact(whey)
+```
+
+and the calculator prints:
+
+```sh
+13763753091226345046315979581580902400000000
+```
+
+The calculator also knows about complex numbers, so that typing:
+
+```sh
+(2+3i) * (4-3i)
+cos(.)
+```
+
+will print:
+
+```sh
+17+6i
+-55.50474777265624667147+193.9265235748927986537i
+```
+
+The calculator can calculate transcendental functions, and accept and
+display numbers in real or exponential format. For example, typing:
+
+```sh
+config("display", 70),
+epsilon(1e-70),
+sin(1)
+```
+
+prints:
+
+```sh
+0.8414709848078965066525023216302989996225630607983710656727517099919104
+```
+
+Calc can output values in terms of fractions, octal or hexadecimal.
+For example:
+
+```sh
+config("mode", "fraction"),
+(17/19)^23
+print
+base(16),
+(19/17)^29
+print
+log(79.3i)
+```
+
+ will print:
+
+```sh
+19967568900859523802559065713/257829627945307727248226067259
+
+0x9201e65bdbb801eaf403f657efcf863/0x5cd2e2a01291ffd73bee6aa7dcf7d1
+
+0x17b5164ac24ee836bf/0xc7b7a8e3ef5fcf752+0x883eaf5adadd26be3/0xc7b7a8e3ef5fcf752i
+```
+
+All numbers are represented as fractions with arbitrarily large
+numerators and denominators which are always reduced to lowest terms.
+Real or exponential format numbers can be input and are converted
+to the equivalent fraction.  Hex, binary, or octal numbers can be
+input by using numbers with leading '0x', '0b' or '0' characters.
+Complex numbers can be input using a trailing 'i', as in '2+3i'.
+Strings and characters are input by using single or double quotes.
+
+Commands are statements in a C-like language, where each input
+line is treated as the body of a procedure.  Thus the command
+line can contain variable declarations, expressions, labels,
+conditional tests, and loops.  Assignments to any variable name
+will automatically define that name as a global variable.  The
+other important thing to know is that all non-assignment expressions
+which are evaluated are automatically printed.  Thus, you can evaluate
+an expression's value by simply typing it in.
+
+Many useful built-in mathematical functions are available.  Use the:
+
+```sh
+help builtin
+```
+
+command to list them.
+
+You can also define your own functions by using the 'define' keyword,
+followed by a function declaration very similar to C.
+
+```sh
+define f2(n)
+{
+	local ans;
+
+	ans = 1;
+	while (n > 1)
+		ans *= (n -= 2);
+	return ans;
+}
+```
+
+Thus the input:
+
+```sh
+f2(79)
+```
+
+will produce:
+
+```sh
+1009847364737869270905302433221592504062302663202724609375
+```
+
+Functions which only need to return a simple expression can be defined
+using an equals sign, as in the example:
+
+```sh
+define sc(a,b) = a^3 + b^3
+```
+
+Thus the input:
+
+```sh
+sc(31, 61)
+```
+
+will produce:
+
+```sh
+256772
+```
+
+Variables in functions can be defined as either 'global', 'local',
+or 'static'.  Global variables are common to all functions and the
+command line, whereas local variables are unique to each function
+level, and are destroyed when the function returns.  Static variables
+are scoped within single input files, or within functions, and are
+never destroyed.  Variables are not typed at definition time, but
+dynamically change as they are used.
+
+For more information about the calc language and features, try:
+
+```sh
+help overview
+```
+
+Calc has a help command that will produce information about
+every builtin function, command as well as a number of other
+aspects of calc usage.  Try the command:
+
+```sh
+help help
+```
+
+for and overview of the help system.  The command:
+
+```sh
+help builtin
+```
+
+provides information on built-in mathematical functions, whereas:
+
+```sh
+help asinh
+```
+
+will provides information a specific function.  The following
+help files:
+
+```sh
+help command
+help define
+help operator
+help statement
+help variable
+```
+
+provide a good overview of the calc language.  If you are familiar
+with C, you should also try:
+
+```sh
+help unexpected
+```
+
+It contains information about differences between C and calc
+that may surprize C programmers.
