step-2mod.sh
  A record of the basic commands necessary to set up the
  step-2mod example, and then to run it, on my desktop running Linux
  and using a common file system.

1) Remove old files created by make.


2) Use cmake to create the Makefile.

-- The C compiler identification is GNU 7.5.0
-- The CXX compiler identification is GNU 7.5.0
-- Check for working C compiler: /usr/bin/cc
-- Check for working C compiler: /usr/bin/cc -- works
-- Detecting C compiler ABI info
-- Detecting C compiler ABI info - done
-- Detecting C compile features
-- Detecting C compile features - done
-- Check for working CXX compiler: /usr/bin/c++
-- Check for working CXX compiler: /usr/bin/c++ -- works
-- Detecting CXX compiler ABI info

-- Detecting CXX compile features - done
-- Autopilot invoked
-- Configuring done

-- Build files have been written to: /home/burkardt/public_html/dealii_src/step-2mod

3) Use 'make run' to compile, link and run the step-1 example.

4) Convert sparsity patterns to PNG files.
