          TestU01: Testing Random Number Generators

***********************************************************

TestU01 is a package implemented in ANSI C. It is designed to make it
reasonably simple to perform statistical tests on arbitrary random
number generators (RNG).

It is copyrighted by Pierre L'Ecuyer.

This is a modified version of the package, part of a BEng project.
Use at your own risk.
The files testu01/bbattery.{tex,c} have been edited.
The directories build and parallel and their files are completely new and not associated with the original package.

---------------------------------------------------------------------------
DIRECTORY STRUCTURE

-- examples:  program examples showing how to use TestU01.

-- testu01:	 source files and user guide. Contains many random number
             generators (RNG), some specific, and others in a generic form.
             It contains also many well-known and not so well-known statistical
             tests for RNG and predefined batteries of tests for RNG.

-- probdist: source files and user guide. Contains probability distributions
             and a few methods useful for statistics computations.

-- mylib:	 source files and user guide. Miscelleanous useful tools.

-- include:	 header files

-- param:	 parameter files for family of generators (modules f*).

DOCUMENTATION

The main documentation of this package was written originally in
Latex format; it has been used to create doc in PDF format. 
In each of the 3 source directories, there is a file named guide....pdf 
containing the documentation on the modules in this directory
and giving a description of the public variables and functions.
The *.pdf file may be viewed with a PDF reader like Acrobat.

In directory testu01, there is a short and a long version of the
user guide: guideshorttestu01.pdf and guidelongtestu01.pdf.
The short version may be sufficient for the typical user.
The longer version contains more details on functions and types and
their possible uses.


---------------------------------------------------------------------------
COMPILATION of the Package:

- Before compiling the package, you may have to set some global constants 
  in file mylib/gdef.tex to their appropriate values if the default values
  are not accepted by your platform (the mylib/gdef.h will be created
  automatically).

- All the header files (*.h) of the package will be created automatically 
  from the corresponding *.tex files when building the package libraries.



---------------- Note for Windows

The packages MinGW32 and MSYS are required to make TestU01 work on Windows.
And the configure command must be called with the option --disable-shared
---------------------------------



- Call configure (or sh ./configure) to configure the package for your system.
  Give also the name of the directory where you want to install the libraries
  and binaries. It is advised to set the install directory completely 
  separate from the package directory.
  
	 ./configure --prefix=<install directory>

  For example, if you want to install it in the directory usr in the
  user's home directory, call (directory usr MUST EXIST)
	 ./configure --prefix=$HOME/usr

  If no prefix is given in the configure command above, then the libraries
  will be installed in the standard directory /usr/local, but only the
  system administrator has the permissions to do that.


- Call
	make
  to compile everything and build the libraries.

- Call
	make install
  to install the libraries in the chosen directory.


---------------------------------------------------------------------------
DOC

If the installation process has worked without glitch, there will be a
subdirectory
   share/TestU01/doc
in the install directory containing the user guides in pdf format. These guides
describe all the public functions and public identifiers of the package.

 
---------------------------------------------------------------------------
USAGE

If the installation process has worked without glitch, there will be a
subdirectory
   share/TestU01/examples
containing a few small example programs. In order to compile the small programs,
the 3 following paths must be added to the environment variables.

LD_LIBRARY_PATH    <install directory>/lib
LIBRARY_PATH       <install directory>/lib
C_INCLUDE_PATH     <install directory>/include

[ If the libraries have been installed in /usr/local, it may be
  necessary for some Unix/Linux systems to redefine these 3 paths.
  More specifically, the environment variables LD_LIBRARY_PATH and LIBRARY_PATH
  point to the /usr/local/lib (or /usr/local/lib64 for x86_64) directory. Use
     echo $LD_LIBRARY_PATH
     echo $LIBRARY_PATH
  to get the current library paths, and check that the appropriate directory is
  included. If it is not included, you need to redefine them as follows. ]

In a c-shell, they can be added or set with

   setenv LD_LIBRARY_PATH <install directory>/lib:${LD_LIBRARY_PATH}
   setenv LIBRARY_PATH <install directory>/lib:${LIBRARY_PATH}
   setenv C_INCLUDE_PATH <install directory>/include:${C_INCLUDE_PATH}

or perhaps simply

   setenv LD_LIBRARY_PATH <install directory>/lib
   setenv LIBRARY_PATH <install directory>/lib
   setenv C_INCLUDE_PATH <install directory>/include


In a Bourne shell, they can be added or set with

   export LD_LIBRARY_PATH=<install directory>/lib:${LD_LIBRARY_PATH}
   export LIBRARY_PATH=<install directory>/lib:${LIBRARY_PATH}
   export C_INCLUDE_PATH=<install directory>/include:${C_INCLUDE_PATH}

or perhaps simply

   export LD_LIBRARY_PATH=<install directory>/lib
   export LIBRARY_PATH=<install directory>/lib
   export C_INCLUDE_PATH=<install directory>/include


Then the small example birth1.c in directory examples can be compiled with
the C compiler

gcc birth1.c -o birth1 -ltestu01 -lprobdist -lmylib -lm


---------------- Note for Windows users -----------------
For MinGW, the user may have to compile-link as

gcc birth1.c -o birth1.exe -ltestu01 -lprobdist -lmylib -lwsock32

---------------------------------------------------------
For Cygwin, before running the program, the user may have to set

export PATH=<install directory>/bin:${PATH}
