description:
make(1): group the command line options and arguments
By having a single struct that holds all command line options and
arguments, it is easy to see in the code when such a command line
argument is modified. It also cleans up the namespace since the command
line options don't follow a common naming style. Having them in a
struct also means that there is a single place for putting the
documentation, not two as before.
The struct also suggests to extract the initialization code out of main,
which is still too large, having more than 400 lines of code and
covering far too many topics.
