// This options struct is a bit unconventional. The sequencer has multiple optional modules which
// can be added, in any combination, to the service. These include, for example, the API server.
// Each of these modules has its own options, which are all required if the module is added but can
// be omitted otherwise. Clap doesn't have a good way to handle "grouped" arguments like this (they
// have something called an argument group, but it's different). Sub-commands do exactly this, but
// you can't have multiple sub-commands in a single command.
//
// What we do, then, is take the optional modules as if they were sub-commands, but we use a Clap
// `raw` argument to collect all the module commands and their options into a single string. This
// string is then parsed manually (using a secondary Clap `Parser`, the `SequencerModule` type) when
// the user calls `modules()`.
//
// One slightly unfortunate consequence of this is that the auto-generated help documentation for
// `SequencerModule` is not included in the help for this top-level type. Users can still get at the
// help for individual modules by passing `help` as a subcommand, as in
// `sequencer [options] -- help` or `sequencer [options] -- help <module>`. This means that IT IS
// BEST NOT TO ADD REQUIRED ARGUMENTS TO THIS TYPE, since the required arguments will be required
// even if the user is only asking for help on a module. Try to give every argument on this type a
// default value, even if it is a bit arbitrary.
