The following options are for SML# compiler development.

-d $\mathrm{[}switch\mathrm{]}$

Set compiler developers’ switch $switch$. if $switch$ is omitted, it goes into verbose mode for compiler developers. If -d without $switch$ is specified together with --help, it prints the list of compiler developers’ switches.

-B $dir$

Set the directory containing compiler configuration file (config.mk) and the SML# standard libraries.
