UCMARS : A User Code with a Multiple-Array System using
           Combinatorial Geometry

1) ABSTRACT
 UCMARS is a user code foe EGS4 which allows the users to
model many rectangular arrays containing a geometry modeled
by a combinbatorial geometry with unlimited array nesting.
 This user code was tested on Sun sparc 20 with Sun OS 4.1.3.

2) INSTALLATION
 The procedure to install this use code is as follows.
   (1) Expanding source programs to hard disk 

       uncompress mars.tar.Z

       tar xvf mars.tar

   (2) "Make" archive of MARS object libralies

       cd ./MARS
       make
       cd ..

    The archiv "mars.a" will be crated in directory ./MARS

   (3) Run ucmars.mor by using ./MARS/mars.a at f77 stage

       humanf.inp -- nars input data.  Read from standard input (unit 5)
       pbody.dat  -- material data.

   (4) Compare result with sample outout (humanf.out)
      
3) Following files are included.
