========================================================================
| In order to compile nauty on systems which include a Unix-like shell
| (which includes MacOSX and Cygwin), you must first run the script
| "configure".  Usually this can be done with the command
|  ./configure
| 
| The configure script will create custom versions of these files:
|   gtools.h makefile naututil.h nauty.h
| Afterwards you can use "make" to compile everything.
| 
| In case you can't run shell scripts, or configure doesn't work for 
| some reason, you need to adjust the configuration by hand:
| For gtools.h, naututil.h, and nauty.h, make sure definitions near the
| start of the file (like HAVE_UNISTD_H and SIZEOF_INT) are all correct.
| For makefile, copy the file makefile.basic to makefile, then check the
| definitions near the start.
| 
| Please notify Brendan McKay <bdm@cs.anu.edu.au> of any problems with
| the configuration and of any hints you might have for other people with
| similar setups as you have.
