+Installing calc from the gziped tarball in 4 easy steps:
 
-    1) Look at the makefile, and adjust it to suit your needs.
+    0)  If your platform supports i686 RPMs, you may want to go to:
 
-       Here are some Makefile hints:
+	    http://www.isthe.com/chongo/src/calc/
 
-	   Select a compiler set by commenting in the appropriate set
-	   of cc options.  As shipped the Makefile assumes a gcc-like
-	   environment such as Linux.  If a more appropriate cc set if
-	   found below, comment out the Linux set and comment in that
-	   set or edit the gcc set or the common cc set as needed.
+	and use these RPMs:
 
-	   You may or may not need RANLIB when building libraries.
-	   As shipped the Makefile assumes RANLIB is needed.
-	   Comment the in/out the RANLIB value if ranlib does
-	   not work or does not exist.
+	    * calc*.i686.rpm
+		- all that is needed if you just want to use calc
 
-	   You may want to change the default pager used by calc.
-	   As shipped the Makefile assumes 'more'.  On your system
-	   you may find 'less' to be a better pager.
+	    * calc-devel-*.i686.rpm
+	        - calc *.h header and *.a lib files for use in other programs
 
-	   Set TOPDIR to be the place under which help files, calc,
-	   include files and calc libs are to be installed.  As shipped
-	   the Makefile assumes a TOPDIR of /usr/local/lib.
+	    * calc.*.src.rpm
+	        - calc source in RPM package form
 
-	   Set BINDIR to the place where calc is installed.  As shipped
-	   the Makefile assumes a BINDIR /usr/local/bin.
+	The following 4 steps apply to calc source tree that comes from either:
+
+		gunzip -c calc-*.tar.gz | tar -xvf -
+
+	or from:
+
+		rpm -ivh calc-*.src.rpm
+		cd /var/tmp
+		gunzip -c /usr/src/redhat/SOURCES/calc-*.tar.gz | tar -xvf -
+
+    1)	Look at the makefile, and adjust it to suit your needs.
+
+	The Makefile, as shipped, is suitable for installation under
+	Linux and Un*x-like environments.  For the most part, the default
+	values should work.  If in doubt, follow the 'When in doubt'
+	suggestion.
+
+	!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
+	! If you are building under Windoz or a Windoz-like environment !
+	! (such as Cygwin or DJGPP), read the README.WINDOWS file.      !
+	!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
+
+	You should determine if these Makefile variables are reasonable:
+
+	    INCDIR		Where the system include (.h) files are kept.
+	    BINDIR		Where to install calc binary files.
+	    LIBDIR		Where to install calc link library (*.a) files.
+	    CALC_SHAREDIR	Where to install calc help, .cal, startup, and
+	    			config files.
+
+	You may want to change the default installation locations for
+	these values, which are based on the 4 values listed above:
+
+	    HELPDIR            where the help directory is installed
+	    CALC_INCDIR        where the calc include files are installed
+	    CUSTOMCALDIR       where custom *.cal files are installed
+	    CUSTOMHELPDIR      where custom help files are installed
+	    CUSTOMINCPDIR      where custom .h files are installed
+	    SCRIPTDIR          where calc shell scripts are installed
+
+	If you want to install calc files under a top level directory,
+	then set the T value:
+
+	    The calc install is performed under $T, the calc build is
+	    performed under /.	The purpose for $T is to allow someone
+	    to install calc somewhere other than into the system area.
+
+	    For example, if:
+
+	    	BINDIR= /usr/bin
+		LIBDIR= /usr/lib
+		CALC_SHAREDIR= /usr/share/calc
+
+	    and if:
+
+	    	T= /var/tmp/testing
+
+	    Then the installation locations will be:
+
+		calc binary files:	/var/tmp/testing/usr/bin
+		calc link library:	/var/tmp/testing/usr/lib
+		calc help, .cal ...:	/var/tmp/testing/usr/share/calc
+		... etc ...		/var/tmp/testing/...
+
+	    If $T is empty, calc is installed under /, which is the same
+	    top of tree for which it was built.  If $T is non-empty, then
+	    calc is installed under $T, as if one had to chroot under
+	    $T for calc to operate.
+
+	Look for the section that starts:
+
+	    ################
+	    # compiler set #
+	    ################
+
+	    Select a compiler set by commenting in the appropriate set
+	    of cc options.  As shipped the Makefile assumes a gcc-like
+	    environment such as Linux.  If a more appropriate cc set if
+	    found below, comment out the Linux set and comment in that
+	    set or edit the gcc set or the common cc set as needed.
+
+	You may want to change these Makrfile variables from their defaults:
+
+	    RANLIB
+
+		You may or may not need RANLIB when building libraries.
+		As shipped the Makefile assumes RANLIB is needed.
+		Comment the in/out the RANLIB value if ranlib does
+		not work or does not exist.
+
+	    CALCPAGER
+
+		You may want to change the default pager used by calc.
+		As shipped the Makefile assumes 'more'.  On your system
+		you may find 'less' to be a better pager.
+
+	    DEBUG
+
+	       Some compilers (to put it mildly) have bugs.  Sometimes the
+	       DEBUG Makefile variable causes the compiler / optimizer to
+	       produce bad code.  Other compilers do just fine.
+
+	       If possible try to use DEBUG=-O3 -g3 (maximum optimization
+	       and debug symbols).  If the calc test fails (see step 3),
+	       try lowering either the -O value and/or the -g3.  Also try
+	       using -Osomething without -g.

+You might want to try using the DJGPP system to compile calc.  See:
+
+	http://www.delorie.com/djgpp/
+
+for DJGPP details and availability.
+
+To compile with DJGPP, one needs to select a number of Makefile
+variable changes.  Eli Zaretskii <eliz at is dot elta dot co dot il>
+recommends the following settings:
+
+	TERMCONTROL= -DUSE_TERMIOS
+	BYTE_ORDER= -DLITTLE_ENDIAN
+	LONG_BITS= 32
+	HAVE_FPOS_POS= -DHAVE_NO_FPOS_POS
+	FPOS_BITS= 32
+	OFF_T_BITS= 32
+	DEV_BITS= 32
+	INODE_BITS= 32
+	HAVE_USTAT= -DHAVE_NO_USTAT
+	HAVE_GETSID= -DHAVE_NO_GETSID
+	HAVE_GETPGID= -DHAVE_NO_GETPGID
+	HAVE_GETTIME= -DHAVE_NO_GETTIME
+	HAVE_GETPRID= -DHAVE_NO_GETPRID
+	HAVE_URANDOM_H= NO
+	ALIGN32= -UMUST_ALIGN32
+	HAVE_MALLOC_H= YES
+	HAVE_STDLIB_H= YES
+	HAVE_STRING_H= YES
+	HAVE_TIMES_H= NO
+	HAVE_SYS_TIMES_H= YES
+	HAVE_TIME_H= YES
+	HAVE_SYS_TIME_H= YES
+	HAVE_UNISTD_H= YES
+	BINDIR= /dev/env/DJDIR/bin
+	INCDIR= /dev/env/DJDIR/include
+	LIBDIR= /dev/env/DJDIR/lib
+	MANDIR= /dev/env/DJDIR/man/man1
+	CATDIR= /dev/env/DJDIR/man/cat1
+	NROFF= groff
+	CALCPATH= .;./cal;~/.cal;${CALC_SHAREDIR};${CUSTOMCALDIR}
+	CALCRC= ${CALC_SHAREDIR}/startup;~/.calcrc;./.calcinit
+	CALCPAGER= less.exe -ci
+	DEBUG= -O2 -gstabs+
+
+The 'Linux set' or 'gcc set' (see the Select your compiler type section)
+should work for DJGPP systems if you set the above Makefile variables.
+
+Look for Makefile comments of the form:
+
+	# Select ...something... for DJGPP.
+
+Follow those recommendations.  In cases where they conflict with
+the above Makefile list, follow the recommendation in the Makefile.

 that are shipped with calc.  See above for example of how to read in
 and execute these files.

+    mul_loop(repeat,x) defined
+    mul_ratio(len) defined
+    best_mul2() defined
+    sq_loop(repeat,x) defined
+    sq_ratio(len) defined
+    best_sq2() defined
+    pow_loop(repeat,x,ex) defined
+    pow_ratio(len) defined
+    best_pow2() defined
+
+    These functions search for an optimal value of config("mul2"),
+    config("sq2"), and config("pow2").  The calc default values of these
+    configuration values were set by running this resource file on a
+    1.8GHz AMD 32-bit CPU of ~3406 BogoMIPS.
+
+    The best_mul2() function returns the optimal value of config("mul2").
+    The best_sq2() function returns the optimal value of config("sq2").
+    The best_pow2() function returns the optimal value of config("pow2").
+    The other functions are just support functions.
+
+    By design, best_mul2(), best_sq2(), and best_pow2() take a few
+    minutes to run.  These functions increase the number of times a
+    given computational loop is executed until a minimum amount of CPU
+    time is consumed.  To watch these functions progress, one can set
+    the config("user_debug") value.
+
+    Here is a suggested way to use this resource file:
+
+	; read alg_config
+	; config("user_debug",2),;
+	; best_mul2(); best_sq2(); best_pow2();
+	; best_mul2(); best_sq2(); best_pow2();
+	; best_mul2(); best_sq2(); best_pow2();
+
+    NOTE: It is perfectly normal for the optimal value returned to differ
+    slightly from run to run.  Slight variations due to inaccuracy in
+    CPU timings will cause the best value returned to differ slightly
+    from run to run.
+
+    One can use a calc startup file to change the initial values of
+    config("mul2"), config("sq2"), and config("pow2").  For example one
+    can place into ~/.calcrc these lines:
+
+	config("mul2", 1780),;
+	config("sq2", 3388),;
+	config("pow2", 176),;
+
+    to automatically and silently change these config values.
+    See help/config and CALCRC in help/environment for more information.

+NAME
+    pmodm127 - calculate q mod 2^(2^127-1)
+
+SYNOPSIS
+    custom("pmodm127", q)
+
+TYPES
+    q		int > 0
+
+    return	int
+
+DESCRIPTION
+
+    This custom function will return the value:
+
+    	q mod 2^(2^127-1)
+
+    This custom function serves as a demonstration of how to write
+    a custom function.  It performs the equivalent of:
+
+	pmod(2, 2^127-1, q)
+
+    The return value is integer in the half open range: [0, q).
+
+    SPECIAL NOTE:
+
+	Can you find a value, q, for which this custom function returns 1?
+	If you do, send the value of q to chongo using the EMail address
+	found at:
+
+	    http://www.isthe.com/chongo/address.html
+
+EXAMPLE
