## Returns a dictionary of all arguments passed after `--` on the command line
|
||
|
|
## arguments take one of 2 forms:
|
||
|
|
## - `--arg` which is a boolean (using `--no-arg` for `false` is possible)
|
||
|
|
## - `--arg=value`. If the value is quoted with `"` or `'`, this function will
|
||
|
|
## unsurround the string
|
||
|
|
## This function does no evaluation and does not attempt to guess the type of
|
||
|
|
## arguments. You will receive either bools, or strings.
