Switch on TOYBOX_DEBUG in menuconfig (toybox global settings menu) +the first time you build and run your new command. If anything is wrong +with your option string, that will give you error messages.
+ +Otherwise it'll just segfault without +explanation when it falls off the end because it didn't find a matching +end parantheses for a longopt, or you put a nonexistent option in a square +bracket grouping... Since these kind of errors can only be caused by a +developer, not by end users, we don't normally want runtime checks for +them. Once you're happy with your option string, you can switch TOYBOX_DEBUG +back off.
