* - Extra whitespace at the beginning and end and between arguments will be ignored
* - Text can be "double" or 'single' quoted
* - The backslash \c \ is used as escape character
* - Outside quotes, any character can be escaped
* - Within double quotes, only escape \c " and backslashes before a \c " or another backslash
* - Within single quotes, no escaping is possible and no special interpretation takes place
*
