Retrieve names of the required system environment variables
Value
A named character vector of the required system environment variables where their names are the package environments that they relate to. Note that the package environments (e.g. 'main' and 'ref') provide runtime information for using the package and should not be confused with the system environment which specifies user-specific variables.
