diff toys/netcat.c @ 233:d4176f3f3835
Zap toys/Config.in and instead create generated/Config.in from contents of
toys/*.c. Move relevant info into comment at the top of each toys/*.c. Also
convert more of Makefile into a thin wrapper around shell scripts that actually
do the work. (Makefile is only still there for the user interface.)
