=head2 Indentation style
To match the indentation of Verilator C++ sources, use 4 spaces per level,
and leave tabs at 8 columns, so every other indent level is a tab stop.
In Emacs, use in your ~/.emacs
(c-set-style "cc-mode")
This sets indentation to the cc-mode defaults. (Verilator predates a
CC-mode change of several years ago which overrides the defaults with GNU
style indentation; the c-set-style undoes that.)
