Compilation
-----------
-If your system supports Linux/i386/ELF/libc5 executables (Linux package)
+If your system supports Linux/i386/ELF/glibc executables (Linux package)
or if you run DOS/Windows (DOS package), you can directly use the included
precompiled binary.
If you use a different system, just recompile the game:
-If you use Linux with gcc or DOS/Windows with djgpp, just try 'make'
+If you use Linux with gcc or DOS or Windows 3.x with djgpp, just try 'make'
which should work without problems.
If you use SUN/Solaris with gcc and GNU make, try 'make solaris'.
+To build the game with SDL support (needed for fullscreen and MOD support),
+type "make sdl". You need at least SDL version 1.1.x and the additional
+SDL libraries SDL_image and SDL_mixer. To get a recent version of the SDL
+library, see http://www.libsdl.org.
+
If the above doesn't work, edit the Makefile in the top level directory.
If it doesn't work either, edit the Makefile in the 'src' subdirectory.
If you had to modify any Makefile to compile it, please drop me a note
-about it to 'aeglos@valinor.owl.de'. Thanks!
+about it to 'info@artsoft.org'. Thanks!
Customization
If you have any comments, additions or modifications to the Makefile(s),
-please send me mail: 'aeglos@valinor.owl.de'. Thanks!

Introduction
============
This is a nice little game with color graphics and sound for your
-Unix system with color X11. You need an 8-Bit color display or better.
-It will not work on black&white systems, and maybe not on gray scale systems.

If you know the game "Boulderdash" (Commodore C64) or "Emerald Mine"
(Amiga) or "Supaplex" (PC), you know what "ROCKS'N'DIAMONDS" is about.
Getting started
===============
-Just 'cd' to the directory 'rocksndiamonds-*' (Unix) or 'rocks-*' (DOS)
-and type 'rocksndiamonds' (Linux) or 'rocks' (DOS/Windows)!
-This works only on Linux and DOS systems, because the included binary was
-compiled for Linux (i386/glibc) (if you have the Unix package) and DOS
-(if you have the DOS/Windows package).
-If you have another Unix system like HPUX, NetBSD or SUN, you first have to
-type 'make' to compile it.

+(The included Linux binary was compiled on a glibc 2.x system based on
+a 2.2.x Linux kernel and XFree86 4.0.x libraries.)

the team (local multiplayer) mode in the setup menu. See below.

+/* An improved random number generation package. In addition to the standard
+ rand()/srand() like interface, this package also has a special state info
+ interface. The initstate() routine is called with a seed, an array of
+ bytes, and a count of how many bytes are being passed in; this array is
+ then initialized to contain information for random number generation with
+ that much state information. Good sizes for the amount of state
+ information are 32, 64, 128, and 256 bytes. The state can be switched by
+ calling the setstate() function with the same array as was initiallized
+ with initstate(). By default, the package runs with 128 bytes of state
+ information and generates far better random numbers than a linear
+ congruential generator. If the amount of state information is less than
+ 32 bytes, a simple linear congruential R.N.G. is used. Internally, the
+ state information is treated as an array of longs; the zeroeth element of
+ the array is the type of R.N.G. being used (small integer); the remainder
+ of the array is the state information for the R.N.G. Thus, 32 bytes of
+ state information will give 7 longs worth of state information, which will
+ allow a degree seven polynomial. (Note: The zeroeth word of state
+ information also has some other information stored in it; see setstate
+ for details). The random number generation technique is a linear feedback
+ shift register approach, employing trinomials (since there are fewer terms
+ to sum up that way). In this approach, the least significant bit of all
+ the numbers in the state table will act as a linear feedback shift register,
+ and will have period 2^deg - 1 (where deg is the degree of the polynomial
+ being used, assuming that the polynomial is irreducible and primitive).
+ The higher order bits will have longer periods, since their values are
+ also influenced by pseudo-random carries out of the lower bits. The
+ total period of the generator is approximately deg*(2**deg - 1); thus
+ doubling the amount of state information has a vast influence on the
+ period of the generator. Note: The deg*(2**deg - 1) is an approximation
+ only good for large deg, when the period of the shift register is the
+ dominant factor. With deg equal to seven, the period is actually much
+ longer than the 7*(2**7 - 1) predicted by this formula. */

-/* An improved random number generation package. In addition to the standard
- rand()/srand() like interface, this package also has a special state info
- interface. The initstate() routine is called with a seed, an array of
- bytes, and a count of how many bytes are being passed in; this array is
- then initialized to contain information for random number generation with
- that much state information. Good sizes for the amount of state
- information are 32, 64, 128, and 256 bytes. The state can be switched by
- calling the setstate() function with the same array as was initiallized
- with initstate(). By default, the package runs with 128 bytes of state
- information and generates far better random numbers than a linear
- congruential generator. If the amount of state information is less than
- 32 bytes, a simple linear congruential R.N.G. is used. Internally, the
- state information is treated as an array of longs; the zeroeth element of
- the array is the type of R.N.G. being used (small integer); the remainder
- of the array is the state information for the R.N.G. Thus, 32 bytes of
- state information will give 7 longs worth of state information, which will
- allow a degree seven polynomial. (Note: The zeroeth word of state
- information also has some other information stored in it; see setstate
- for details). The random number generation technique is a linear feedback
- shift register approach, employing trinomials (since there are fewer terms
- to sum up that way). In this approach, the least significant bit of all
- the numbers in the state table will act as a linear feedback shift register,
- and will have period 2^deg - 1 (where deg is the degree of the polynomial
- being used, assuming that the polynomial is irreducible and primitive).
- The higher order bits will have longer periods, since their values are
- also influenced by pseudo-random carries out of the lower bits. The
- total period of the generator is approximately deg*(2**deg - 1); thus
- doubling the amount of state information has a vast influence on the
- period of the generator. Note: The deg*(2**deg - 1) is an approximation
- only good for large deg, when the period of the shift register is the
- dominant factor. With deg equal to seven, the period is actually much
- longer than the 7*(2**7 - 1) predicted by this formula. */
-
-
-
-/* For each of the currently supported random number generators, we have a
- break value on the amount of state information (you need at least thi
- bytes of state info to support this random number generator), a degree for
- the polynomial (actually a trinomial) that the R.N.G. is based on, and
- separation between the two lower order coefficients of the trinomial. */
