/**
* Mechanisms to configure and run selenium via the command line. There
* are two key classes {@link org.openqa.selenium.cli.CliCommand} and
* {@link org.openqa.selenium.grid.config.HasRoles}. Ultimately, these are used to
* build a {@link org.openqa.selenium.grid.config.Config} instance, for
* which there are strongly-typed role-specific classes that use a
* {@code Config}, such as
* {@link org.openqa.selenium.grid.node.docker.DockerOptions}.
*
*
Assuming your {@code CliCommand} extends
* {@link org.openqa.selenium.grid.TemplateGridCommand}, the process for
* building the set of flags to use is:
*
* - The default flags are added (these are
* {@link org.openqa.selenium.grid.server.HelpFlags} and
* {@link org.openqa.selenium.grid.config.ConfigFlags}
*
- {@link java.util.ServiceLoader} is used to find all implementations
* of {@link org.openqa.selenium.grid.config.HasRoles} where
* {@link org.openqa.selenium.grid.config.HasRoles#getRoles()} is contained
* within {@link org.openqa.selenium.cli.CliCommand#getConfigurableRoles()}.
*
- Finally all flags returned by
* {@link org.openqa.selenium.grid.TemplateGridCommand#getFlagObjects()}
* are added.
*
*
* The flags are then used by JCommander to parse the command arguments.
* Once that's done, the raw flags are converted to a
* {@link org.openqa.selenium.grid.config.Config} by combining all of the
* flag objects with system properties and environment variables. This
* implies that each flag object has annotated each field with
* {@link org.openqa.selenium.grid.config.ConfigValue}.
*
*
Ultimately, this means that flag objects have all (most?) fields
* annotated with JCommander's {@link com.beust.jcommander.Parameter}
* annotation as well as {@code ConfigValue}.
