While creating the sourcefile, the "grouping" commands use the term "group"
for an aggregate of items (e.g. "\defgroup" or "\addtogroup"). In the
output, these groups are called "modules" instead, which I consider
unnecessary confusing.
How about adding aliases for the functions with the term "module" instead of
"group" (e.g. "\defmodule" as alias for "\defgroup")? I'd even go so far to
suggest outphasing the "group" commands in the (far) future.
