# Revision 3.7 1994/11/23 14:50:47 sander
# #include <limits.h> added to get MAX_INT and MIN_INT.
#
# Revision 3.6 1994/08/08 16:01:47 sander
# Attributes xraster, xlraster, yraster added.
#
# Revision 3.5 1994/08/02 15:36:12 sander
# CHECKNODE option added to allow tracing of properties
# of one single node. For debugging only.
#
# Revision 3.4 1994/06/07 14:09:59 sander
# Splines implemented.

#
# Revision 3.2 1994/03/02 11:48:54 sander
# Layoutalgoritms mindepthslow, maxdepthslow, minindegree, ... mandegree
# added.

/* Debugging On or Off ?
* We have three kinds of debugging:
* a) Behaviour tracing: a lot of messages nearly on every
* function entry are produced if DEBUG is switched on.
* b) Assertion checking: only if an assertion fails, an
* appropriate message is produced.
* c) Node tracing: This is basically the same as the behaviour
* tracing. At each function entry, the status of a node
* will be printed. This happens if CHECKNODE is defined.
* See step0 for the selection of the node to be traced.
* Behaviour or node tracing is only needed in very serious cases.
* The macros "debuggingmessage" can be redefined to do some special
* tests on every entry.
* Assertion checking can always be done, because it is silent
* as long as no error occurs. But it consumes runtime.
* This all can also be defined in the head of a module before
* #include "globals.h", to debug only this module.
