The csquotes Package

\DeclareQuoteStyle[official]{newspeak}
{\textquotedblleft}{\textquotedblright}
{\textquoteleft}{\textquoteright}
\DeclareQuoteStyle[unofficial]{newspeak}
{\textquotedblright}{\textquotedblleft}
{\textquoteright}{\textquoteleft}
The ocial variant should be the default for this style. There is no need to copy the
definition of the official variant to accomplish that. We simply define an alias
labeled newspeak which points to the desired variant:
\DeclareQuoteAlias[official]{newspeak}{newspeak}
The reason why we are using variants and aliases instead of two independent styles
will become clear in a moment. Suppose that the babel package oered support
for Newspeak, but this language was known to babel as otherspeak:
\DeclareQuoteAlias{newspeak}{otherspeak}
This is an example of a second-level alias pointing to a first-level alias. If the current
language is otherspeak, the above aliases will be expanded as follows:
otherspeak = newspeak = newspeak/official
We also define a new package option to choose a style variant:
\DeclareQuoteOption{newspeak}
This will add a new package option with a key called newspeak. The value of
this option may be any variant of the newspeak style defined in the configuration
file. In this example, there are two possible values: official and unofficial. To
select the default or the alternative style for the entire document we use:
\usepackage[style=newspeak]{csquotes}
\usepackage[style=newspeak,newspeak=unofficial]{csquotes}
To select the default or the alternative style with multilingual support we use:
\usepackage[babel]{csquotes}
\usepackage[babel,newspeak=unofficial]{csquotes}
The base style must be implemented as an alias in this case since the newspeak
option will select a variant by redefining and thus overwriting the newspeak alias.
Since the otherspeak alias points to newspeak and not directly to any backend
style, using the newspeak option will also have the desired eect if multilingual
support is enabled. Note that there are some style names which have a special
meaning. See § 10.9 for details.
9.2 Using Quotation and Citation Hooks
Style guides for writers usually make detailed provisions concerning the formatting
of quotations and citations, including rules dealing with punctuation placement.
This section will discuss some typical usage scenarios, using hooks and other facilities
introduced in §§ 8.7, 8.8, 8.9. In the examples below, we assume the following
