+\ProvidesFile{csquotes.cfg}[2005/08/29 v3.1 csquotes configuration]
+
+% Put your definitions here.
+
+\endinput
+
+% What follows are examples of what you will typically do in this
+% file. Note that you need to move the examples above \endinput if
+% you want to try them out.
+
+% PRESETTING PACKAGE OPTIONS
+%
+% Use \ExecuteOptions to preset package options if you are not
+% satisfied with the built-in defaults. Options given here will be
+% processed before any options specified in the document preamble.
+% You may override them anytime with \usepackage in the preamble.
+
+\ExecuteOptions{babel=true,strict=true}
+
+% CHANGING THE DEFAULT PARAMETERS
+%
+% All preset values may be changed in the document preamble as
+% usual. The following values are the built-in defaults:
+
+\SetBlockEnvironment{quote}
+\SetBlockThreshold{3}
+\SetCiteCommand{\cite}
+
+% SETTING UP A NEW QUOTE STYLE
+
+% Defining a new style with several variants:
+
+\DeclareQuoteStyle[quotes]{example}% [variant]{style}
+ {\textquotedblleft}% opening outer mark
+ {\textquotedblright}% closing outer mark
+ {\textquoteleft}% opening inner mark
+ {\textquoteright}% closing inner mark
+\DeclareQuoteStyle[quotes*]{example}
+ {\quotedblbase}
+ {\textquotedblright}
+ [0.1em]% kern adjoining marks
+ {\quotesinglbase}
+ {\textquoteright}
+\DeclareQuoteStyle[everypar]{example}
+ {\guillemotleft}
+ [\guilsinglleft]% middle outer mark
+ {\guillemotright}
+ {\textquotedblleft}
+ [\textquoteleft]% middle inner mark
+ {\textquotedblright}
+\DeclareQuoteStyle[everyline]{example}
+ [\seteverylineleft{\guillemotleft}]% requires Omega
+ {\guillemotleft}
+ {\guillemotright}
+ {\guilsinglleft}
+ {\guilsinglright}
+\DeclareQuoteStyle[everyline*]{example}
+ [\seteverylineright{\guillemotright}]% requires Omega
+ {\guillemotleft}
+ {\guillemotright}
+ {\guilsinglleft}
+ {\guilsinglright}
+
+% Defining the default variant of the style:
+
+\DeclareQuoteAlias[quotes]{example}{example}
+
+% Defining a second-level alias:
+
+\DeclareQuoteAlias{example}{demo}
+
+% Adding a package option for a style:
+
+\DeclareQuoteOption{example}
+
+% DEFINING ENVIRONMENTS FOR PARAGRAPH QUOTATIONS
+
+% Here are some alternative environments for paragraph quotations
+% (block and display), as discussed in the tutorial. The first one
+% decreases the font size of the `quote' environment by one step:
+
+\RequirePackage{relsize}
+
+\newenvironment*{smallquote}
+ {\quote\smaller}
+ {\endquote}
+
+\SetBlockEnvironment{smallquote}
+
+% This environment forces indentation after all paragraph quotations:
+
+\newenvironment*{paraquote}
+ {\begingroup\quote}
+ {\endquote\endgroup}
+
+\SetBlockEnvironment{paraquote}
+
+% The last environment combines the previous ones:
+
+\RequirePackage{relsize}
+
+\newenvironment*{smallparaquote}
+ {\begingroup\quote\smaller}
+ {\endquote\endgroup}
+
+\SetBlockEnvironment{smallparaquote}

+% AUTHOR INTERFACE
+
+% Controlling active quotes
+
+% This package provides three commands for class and package authors
+% who need to temporarily disable the active quotes for some reason.
+%
+% \@disablequotes
+%
+% This command restores the status quo ante of all active quotes.
+% This can mean one of two things:
+%
+% 1) If a character had been active when it was defined as active
+% quote, its previous definition will be restored.
+%
+% 2) If a character had not been active when it was defined as active
+% quote, its previous category code will be restored.
+%
+% Note that all active quotes are made active \AtBeginDocument hence
+% you will only need \@disablequotes if you're defining anything
+% \AtBeginDocument or later.
+%
+% \@restorequotes
+%
+% This command restores csquotes's definitions of all active quotes
+% and makes them active. The category codes of delimiter characters
+% (used for block quotes) are also restored if they have changed.
+%
+% All changes made by \@disablequotes and \@verbatimquotes are local
+% and may thus be restricted to a group. If you use proper grouping
+% you may omit \@restorequotes.
+%
+% The author commands \@restorequotes and \@disablequotes differ from
+% the user commands \RestoreQuotes and \DisableQuotes in two ways:
+%
+% 1) When used in the preamble, they will do nothing (the user
+% commands would issue a warning since the active quotes are not
+% yet defined at this point).
+%
+% 2) When used in the document body, they will essentially behave
+% like the user commands, except that all informational messages
+% are suppressed. The author commands will work quietly behind the
+% scenes.

+% \@verbatimquotes
+%
+% For verbatim environments and comparable applications, use
+% \@verbatimquotes instead of \@disablequotes. \@verbatimquotes
+% redefines the active quotes in a way that it suitable for a
+% verbatim context. It will do the following:
+%
+% 1) If a character is in the Ascii range (character code <128), it
+% will be redefined so that it expands to itself with category
+% code 12.
+%
+% 2) If a character is not in the Ascii range, there are two
+% possibilities:
+%
+% a) If the character had been active when it was defined as
+% active quote, it will be redefined so that it expands to its
+% previous definition.
+%
+% b) If the character had not been active when it was defined as
+% active quote, it will be redefined so that it expands to
+% itself with its previous category code.
+%
+% In addition to that, all Ascii characters are added to LaTeX's
+% \dospecials list (which may override 1 above, but yield the same
+% result). Non-Ascii characters are not added to \dospecials and may
+% remain active, allowing the inputenc package to handle them in a
+% verbatim context (due to 2a above, which implies that inputenc must
+% be loaded before any active quotes are defined). Case 2b is usually
+% undesirable in a verbatim context. However, if inputenc is loaded
+% and the input encoding is declared properly, this will not happen.
+%
+% \@verbatimquotes is independent of any \dospecials processing. You
+% may typeset all active quotes verbatim by using \@verbatimquotes
+% exclusively. The advantage of \@verbatimquotes is that it does not
+% depend on any category code changes. In contrast to \dospecials and
+% \@makeother, the following is perfectly possible:
+%
+% \newcommand{\printverbquotes}[1]{{\@verbatimquotes #1}}
+%
+% Note that the standard LaTeX verbatim environments as well as all
+% environments defined by way of the verbatim and fancyvrb packages
+% are catered for automatically. When using an environment provided
+% by these packages or when defining new environments with the aid of
+% one of them, there is no need to add \@verbatimquotes explicitly.
+% This also applies to the \verb command and the shortvrb package.
+
+% Frontend to internal marks
+
+% In some cases it may be desirable to gain access to the internal
+% quotation marks of this package without any grouping or nesting
+% control. They may be accessed by way of the following commands:
+%
+% \textooquote opening outer quotation mark
+% \textmoquote middle outer quotation mark
+% \textcoquote closing outer quotation mark
+%
+% \textoiquote opening inner quotation mark
+% \textmiquote middle inner quotation mark
+% \textciquote closing inner quotation mark
+%
+% These commands will simply print the respective quotation mark as
+% defined with \DeclareQuoteStyle. Note that the initialization hooks
+% for the respective quotation style are not expanded in this case.
+% The internal marks will reflect all changes of the quotation style.
+% If the multilingual interface is enabled, they are also synced with
+% the current language.
