This document describes how to generate the C files 
from the M4 templates, mostly intended for developers.

- Appropriate make.inc definition must first be supplied.
  There are several sample make.incs for various platforms
  provided.  Or you can try to have autoconf guess them for
  you; to do this you need to do

    autoconf
    ./configure

  This will create a make.inc appropriate for the compiler(s) 
  found.  This will also create a Makefile from Makefile.m4.
  You can specify which compiler to use by CC and FC environment 
  variables.  For details, see "./configure --help".

- If make.inc was configured manually, create the top-level 
  Makefile is generated from Makefile.m4.  Just do 
  "m4 Makefile.m4 >Makefile"
  
- Then run "make makefiles".  This will generate all
  the makefiles in various directories from m4 template.

- Then run "make sources test-sources".  This will create
  all the C source files for both XBLAS library code and 
  testing code.
