For example, \teTeX\ users run \verb|texhash| or % \verb|mktexlsr|. % % \subsection{Some details for the interested} % % \paragraph{Attached source.} % % The PDF documentation on CTAN also includes the % \xfile{.dtx} source file. It can be extracted by % AcrobatReader 6 or higher. Another option is \textsf{pdftk}, % e.g. unpack the file into the current directory: % \begin{quote} % \verb|pdftk classlist.pdf unpack_files output .| % \end{quote} % % \paragraph{Unpacking with \LaTeX.} % The \xfile{.dtx} chooses its action depending on the format: % \begin{description} % \item[\plainTeX:] Run \docstrip\ and extract the files. % \item[\LaTeX:] Generate the documentation. % \end{description} % If you insist on using \LaTeX\ for \docstrip\ (really, % \docstrip\ does not need \LaTeX), then inform the autodetect routine % about your intention: % \begin{quote} % \verb|latex \let\install=y\input{classlist.dtx}| % \end{quote} % Do not forget to quote the argument according to the demands % of your shell. % % \paragraph{Generating the documentation.} % You can use both the \xfile{.dtx} or the \xfile{.drv} to generate % the documentation. The process can be configured by the % configuration file \xfile{ltxdoc.cfg}. For instance, put this % line into this file, if you want to have A4 as paper format: % \begin{quote} % \verb|\PassOptionsToClass{a4paper}{article}| % \end{quote} % An example follows how to generate the % documentation with pdf\LaTeX: % \begin{quote} %\begin{verbatim} %pdflatex classlist.dtx %makeindex -s gind.ist classlist.idx %pdflatex classlist.dtx %makeindex -s gind.ist classlist.idx %pdflatex classlist.dtx %\end{verbatim} % \end{quote} % % \section{Catalogue} % % The following XML file can be used as source for the % \href{http://mirror.ctan.org/help/Catalogue/catalogue.html}{\TeX\ Catalogue}. % The elements \texttt{caption} and \texttt{description} are imported % from the original XML file from the Catalogue. % The name of the XML file in the Catalogue is \xfile{classlist.xml}. % \begin{macrocode} %<*catalogue> classlist Record classes used in a document.
