 Identical to `getopts`, `getopts_long` will parse options and their possible arguments. It will stop parsing on the first non-option argument (a string that doesn't begin with a hyphen (`-`) that isn't an argument for any option in front of it). It will also stop parsing when it sees the `--` (double-hyphen) as a stand-alone argument.
 
-> IMPORTANT: IMPORTANT: There’s only one exception to the rule that says getopts_long behaves like getopts: when handling `-` within short options!
+> ⚠️ **IMPORTANT**
 >
-> To support long options, getopts_long provides its own implementation for `-` option, which means the user can no longer define `-` as part of the short option OPTSPEC.
+> To support long options and enforce identical behaviour between getopts and getopts_long when handling hyphens, getopts_long provides its own implementation for `-` option. This means that the user can no longer include a hyphen (`-`) within short option OPTSPEC.
