798- The parsing of arguments works as follows: if it encounters a ` " ` or a ` ' ` , it will continue
799- until it finds the character unescaped (without a prepending ` \ ` ). If not inside a string, a
800- whitespace character will also split arguments. Example:
801- 802- ``` text
803- "hello 'a'\" ok" how are 'you today?'
804- ```
805- 806- will be split as follows:
807- 808- ``` text
809- [
810- "hello 'a'\" ok",
811- "how",
812- "are",
813- "you today?",
814- ]
815- ```
798+ In order to pass multiple arguments to the underlying compiler,
799+ pass ` --doctest-build-arg ARG ` for each argument ` ARG ` .
