file. +% \item[\CTAN{macros/latex/contrib/oberdiek/ifvtex.pdf}] Documentation. +% \end{description} +% +% \paragraph{Unpacking.} The \xfile{.dtx} file is a self-extracting +% \docstrip\ archive.

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 ifvtex.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 intension: +% \begin{quote} +% \verb|latex \install=y\input{ifvtex.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 ifvtex.dtx +%makeindex -s gind.ist ifvtex.idx +%pdflatex ifvtex.dtx +%makeindex -s gind.ist ifvtex.idx +%pdflatex ifvtex.dtx +%\end{verbatim} +% \end{quote} +% +% \begin{History} +% \begin{Version}{2001/09/26 v1.0} +% \item +% First public version. +% \end{Version} +% \begin{Version}{2006/02/20 v1.1} +% \item +% DTX framework. +% \item +% Undefined tests changed. +% \end{Version} +% \end{History} +% +% \PrintIndex +% +% \Finale +\endinput |
