+ DEMONSTRATION CALCULATOR PROGRAM
+
+
+This is a simple program, meant only to show one way to use GMP with yacc
+and lex to make a calculator. Usage and comments on the implementation can
+be found in calc.y.
+
+Within a GMP build tree, the generated Makefile can be used to build the
+program,
+
+ make calc
+
+(or on a DOS system, "make calc.exe").
+
+Elsewhere, once GMP has been installed, the program can be compiled with for
+instance
+
+ gcc calc.c calclex.c -lgmp -o calc
+
+Or if GNU readline is used then
+
+ gcc calc.c calclex.c calcread.c -lgmp -lreadline -o calc
+
+(again, on a DOS system "-o calc.exe").
+
+Readline support can be enabled or disabled in calc-config.h. That file is
+created by the GMP ./configure based on the --with-readline option. The
+default is --with-readline=detect, which means to use readline if available.
+"yes" can be used to force it to be used, or "no" to not use it.
+
+The supplied calc.c was generated by GNU bison, but a standard yacc should
+work too.
+
+The supplied calclex.c was generated by GNU flex, but a standard lex should
+work too. The readline support may or may not work with a standard lex (see
+comments with input() in calcread.c). Note also that a standard lex will
+require its library "-ll" on the compile command line. "./configure" sets
+this up in the GMP build tree Makefile.

+/* This is a simple program, meant only to show one way to use GMP for this
+ sort of thing. There's few features, and error checking is minimal.
+ Standard input is read, calc_help() below shows the inputs accepted.
+
+ Expressions are evaluated as they're read. If user defined functions
+ were wanted it'd be necessary to build a parse tree like pexpr.c does, or
+ a list of operations for a stack based evaluator. That would also make
+ it possible to detect and optimize evaluations "mod m" like pexpr.c does.
+
+ A stack is used for intermediate values in the expression evaluation,
+ separate from the yacc parser stack. This is simple, makes error
+ recovery easy, minimizes the junk around mpz calls in the rules, and
+ saves initializing or clearing "mpz_t"s during a calculation. A
+ disadvantage though is that variables must be copied to the stack to be
+ worked on. A more sophisticated calculator or language system might be
+ able to avoid that when executing a compiled or semi-compiled form.
+
+ Avoiding repeated initializing and clearing of "mpz_t"s is important. In
+ this program the time spent parsing is obviously much greater than any
+ possible saving from this, but a proper calculator or language should
+ take some trouble over it. Don't be surprised if an init/clear takes 3
+ or more times as long as a 10 limb addition, depending on the system (see
+ the mpz_init_realloc_clear example in tune/README). */

+/* This is a simple program, meant only to show one way to use GMP for this
+ sort of thing. There's few features, and error checking is minimal.
+ Standard input is read, calc_help() below shows the inputs accepted.
+
+ Expressions are evaluated as they're read. If user defined functions
+ were wanted it'd be necessary to build a parse tree like pexpr.c does, or
+ a list of operations for a stack based evaluator. That would also make
+ it possible to detect and optimize evaluations "mod m" like pexpr.c does.
+
+ A stack is used for intermediate values in the expression evaluation,
+ separate from the yacc parser stack. This is simple, makes error
+ recovery easy, minimizes the junk around mpz calls in the rules, and
+ saves initializing or clearing "mpz_t"s during a calculation. A
+ disadvantage though is that variables must be copied to the stack to be
+ worked on. A more sophisticated calculator or language system might be
+ able to avoid that when executing a compiled or semi-compiled form.
+
+ Avoiding repeated initializing and clearing of "mpz_t"s is important. In
+ this program the time spent parsing is obviously much greater than any
+ possible saving from this, but a proper calculator or language should
+ take some trouble over it. Don't be surprised if an init/clear takes 3
+ or more times as long as a 10 limb addition, depending on the system (see
+ the mpz_init_realloc_clear example in tune/README). */
