%% == Required                 ==
%% 'langcode' is based on \ctanpkgref{dowith}:
\RequirePackage{dowith}
%% 
%% == General Commands         ==
%% |\uselangcode{&lt;lcode&gt;}| \ sets `\langcode' to &lt;lcode&gt;, runs 
%% `\langcodeadjust' on the items stored in `\langcodedependent', 
%% and finally executes what is stored in `\langcodeextras':
\def\uselangcode#1{%
    \def\langcode{#1}%                                  %% 2012/01/07:
    \DoWithAllIn\langcodeadjust\langcodedependent
    \langcodeextras} 
%% |\langcodeadjust\&lt;letters&gt;| \ defines `\&lt;letters&gt;' to expand to 
%% `\&lt;lcode&gt;&lt;letters&gt;':
\def\langcodeadjust#1{%
%     \edef#1{\expandafter\noexpand
%                 \csname\langcode
    %% &lt;- 2012/09/17 -&gt;
    \edef#1{\withcsname\noexpand \langcode
                    \expandafter\@gobble\string#1\endcsname}}
%% 
%% == Sample Settings          == 
%% Such settings once should be in some \file{.cfg} file TODO
%% === What Must Be Varied    ===
%% |\langcodedependent| \ is a list of commands that 
%% must be adjusted:                                    %% ready 2012/09/20
\def\langcodedependent{%                                %% 2012/01/07
    \langcodeextras\dqtd\qtd\pardash\lastrev\totopofpage
    \monthname}                                         %% 2012/01/17
%%
%% === English vs. German     ===
%% ==== Months ====
%% |\enmonthname{&lt;num&gt;}| yields the English name of the &lt;num&gt;th month 
%% of the year:
\def\enmonthname#1{%
    \ifcase #1\or
        January\or February\or March\or    April\or
            May\or June\or     July\or     August\or
      September\or October\or  November\or December%
    \fi}
%% |\demonthname{&lt;num&gt;}| yields the \emph{German} name of the &lt;num&gt;th month 
%% month of the year:
\def\demonthname#1{%
    \ifcase #1\or
         Januar\or Februar\or  M\"arz\or   April\or
            Mai\or Juni\or     Juli\or     August\or
      September\or Oktober\or  November\or Dezember%
    \fi}
%% ==== Quotes ====
%% For |\dqtd| settings, see (load)                     %% load 2012/09/20
%% 'catchdq' (\ctanpkgref{catcodes} bundle).\footnote{% %%      2012/09/20
%%   The test below required loading 'catchdq' \emph{earlier} 
%%   than 'langcode'.} 
%% % while |\qtd| settings are in 'blog.sty' (\ctanpkgref{morehype} bundle).
%% |\enqtd{&lt;en-text&gt;}| and |\deqtd{&lt;de-text&gt;}| 
%% (overridable, e.g., with 'blog.sty'):
\ifx\deqtd\undefined \def\deqtd#1{\glq#1\grq} \fi
\ifx\enqtd\undefined \def\enqtd#1{`#1'}       \fi
%% You may get `\glq' and `\grq' from \CtanPkgRef{ngerman}{ngerman.sty}
%% \[(`\usepackage{ngerman}\originalTeX'\]
%% if needed. Here is a little 
%% \dqtd{tessst \qtd{inner}}, 
%% due to the default |\uselangcode{en}|, we now issue |\uselangcode{de}|
%% \let\delangcodeextras\empty
%% \uselangcode{de}to get
%% \dqtd{tessst \qtd{inner}}. 
%% ==== Dashes ====
%% I introduced |\pardash| thinking of 
%% (German \dqtd{Gedankenstrich} and)
%% long dashes as a weak version of a paragraph break. 
%% \uselangcode{en}
%% A paragraph break somehow means moving from one thought 
%% to another\pardash almost the same what a long dash may 
%% mean.\pardash Here I have switched to \qtd{`en'} 
%% again, in order to get |\enpardash| by |\pardash|:
\ifx\enpardash\undefined \let\enpardash\textemdash \fi
%% \uselangcode{de}
%% The \dqtd{Gedankenstrich} |\depardash| is not as long 
%% \uselangcode{en}
%% as the \dqtd{thought dash}\uselangcode{de}\pardash er ist nur 
%% halb so lang\uselangcode{en}\pardash but it is surrounded 
%% by regular spaces:
\ifx\depardash\undefined \def\depardash{ \textendash\space} \fi
%% Some people prefer a so-called \dqtd{\Wikiref{hair space}}
%% surrounding the long dash. 
%% ==== Wikipedia ====
%% The previous Wikipedia link was obtained by |\Wikiref{hair space}|, 
%% working like |\Wikienref{hair space}|. This is an example of how 
%% \ctanpkgref{texlinks} makes use of |\uselangcode{&lt;two-chars&gt;}|.
%% ==== 'blog.sty' ====
%% In the present sample of \ |\langcodedependent|, \ 
%% \[|\lastrev|\quad\mbox{and}\quad|\totopofpage|\] remain. 
%% I use them for \acro{HTML} with 'blog.sty'\pardash sorry, 
%% at present I cannot afford separating 
%% settings for a wider audience from my own ones.
%% 
%% === Other Settings         ===
%% I haven't used English extras so far:
\let\enlangcodeextras\empty                      %% \empty 2012/01/17
%% With German, I have used the \ctanpkgref{dhua} package 
%% for certain abbrevations:
\def\delangcodeextras{\RequirePackage{dhua}}
%% However, this setting disables `\uselangcode{de}' after 
%% `\begin{document}'---which has not a problem with 'blog.sty', 
%% where I use it daily. For the tests above, 
%% I \emph{emptied} `\delangcodeextras'.
%% I had not thought of changing the language \emph{within} 
%% one document before.
%% 
%% == Default Language Code ==
%% The default `\langcode' is \qtd{`en'} for English:
\uselangcode{en}
%% == Leaving the Package File ==
\endinput
