 pst-math: PostScript extension for mathematical functions:
 
-Save the files pst-math.sty|pro|tex in a directory, which is part of your 
-local TeX tree. The pro file should go into $TEXMF/dvips/pstricks/
-Then do not forget to run texhash to update this tree.
-For more information  see the documentation of your LATEX distribution 
-on installing packages into your local TeX system or read the 
-TeX Frequently Asked Questions:
-(http://www.tex.ac.uk/cgi-bin/texfaq2html?label=instpackages).
+The macros for random numbers cannot be used with xelatex!
 
-pst-math needs pst-plot (pstricks-add) and pstricks, which should 
-be part of your local TeX installation, otherwise get it from a 
-CTAN server, f.ex. ftp://ftp.ctan.org
+hvoss@tug.org
 
-PSTricks is PostScript Tricks, the documentation cannot be run
-with pdftex, use the sequence latex->dvips->ps2pdf.

+\section{Random numbers}
+Package \LPack{pst-math} supports the creation of random number lists where a number will
+appear only once.

+\Lcs{makeSimpleRandomNumberList}\% multiple values possible\\
+\Lcs{makeRandomNumberList}      \% no multiple values!\\
+\Lcs{getNumberFromList}\Largb{number}
+\end{BDef}
+
+The list of the random numbers is \Lcs{RandomNumbers}, a comma separated list of the values.
+It can be used for own purpuses.

+
+In the next example a random number appears only \emph{once} in the list. There no multiple
+numbers:
