Plain “quotes”

Plain double quotes ("text") become proper, language-aware quotation marks via csquotes' \MakeOuterQuote.

Please use the \enquote{enquote command} to quote something.
Quoting with "`quote"' or ``quote'' also works.

The feature "MakeOuterQuote" is also enabled, which enables "plain" double quotes to correctly enquote.
See \url{https://tex.stackexchange.com/a/150958/9075} for details on that solution.

% For easy quotations: \enquote{text}
