10 The current idea of the relation between PRESOLVE_DEBUG and
11 PRESOLVE_CONSISTENCY is that PRESOLVE_CONSISTENCY triggers the consistency
12 checks and PRESOLVE_DEBUG triggers consistency checks and output.
13 This isn't always true in the code, but that's the goal. Really,
14 the whole compile-time scheme should be replaced with something more
15 user-friendly (control variables that can be changed during the run).
16
17 Also floating about are PRESOLVE_SUMMARY and COIN_PRESOLVE_TUNING.
