Programs to generate the distribution of
mean square distances between random walks
walks may be either self avoiding or not

mean square distances may be computed from distance matrices or from
kind of absolute moves

two programs are provided to create the distribution data
  
  walks
    generates random walks and outputs the distances
  hist
    computes histogram from the output of walks (e.g. suitable for gnuplot)

the programs may be configured by defining constants in the program text,
short explanation of constants is given by comments

(after configuration) compile with
   make

generate input for gnuplot with
   walks | hist > test

show distribution with
   gnuplot
   and in gnuplot type, e.g.
       plot "test" with boxes
