From 32d5cfe8f4f4bd9647d36fc0f609479f02311103 Mon Sep 17 00:00:00 2001
From: Marc Espie <espie@cvs.openbsd.org>

Subject: Synch with my current work. Numerous changes: - generate can build
 several tables - style cleanup - statistics code - use variable names
 throughout (struct Name) - recursive variables everywhere - faster parser
 (pass buffer along instead of allocating multiple copies) - correct parser.
 Handles comments everywhere, and ; correctly - more string intervals -
 simplified dir.c, less recursion. - extended for loops - sinclude() -
 finished removing extra junk from Lst_* - handles ${@D} and friends in a
 simpler way - cleaned up and modular VarModifiers handling. - recognizes some
 gnu Makefile usages and errors out about them.

Additionally, some extra functionality is defined by FEATURES. The set of
functionalities is currently hardcoded to OpenBSD defaults, but this may
include support for some NetBSD extensions, like ODE modifiers.

Backed by miod@ and millert@, who finally got sick of my endless patches...
