/**

|
* @brief A _very_ basic Qt .env file parser.
|
|
*
|
|
* This function re-invents the wheel to save adding a library dependency.
|
|
* It does not support many things that a proper .env parser would, such as
|
|
* trailing comments, escaping characters, multiline values, etc.
|
|
*
|
|
* If this function is not sufficient, replace it with a library such as:
