the packages of the bundle `oberdiek' +% are also available in a TDS compliant ZIP archive. There +% the packages are already unpacked and the documentation files +% are generated. The files and directories obey the TDS standard. +% \begin{description} +% \item[\CTAN{install/macros/latex/contrib/oberdiek.tds.zip}] +% \end{description} +% \emph{TDS} refers to the standard ``A Directory Structure +% for \TeX\ Files'' (\CTAN{tds/tds.pdf}). Directories +% with \xfile{texmf} in their name are usually organized this way. +% +% \subsection{Bundle installation} +% +% \paragraph{Unpacking.} Unpack the \xfile{oberdiek.tds.zip} in the +% TDS tree (also known as \xfile{texmf} tree) of your choice. +% Example (linux): +% \begin{quote} +% |unzip oberdiek.tds.zip -d ~/texmf| +% \end{quote} +% +% \paragraph{Script installation.} +% Check the directory \xfile{TDS:scripts/oberdiek/} for +% scripts that need further installation steps. +% Package \xpackage{attachfile2} comes with the Perl script +% \xfile{pdfatfi.pl} that should be installed in such a way +% that it can be called as \texttt{pdfatfi}. +% Example (linux): +% \begin{quote} +% |chmod +x scripts/oberdiek/pdfatfi.pl|\\ +% |cp scripts/oberdiek/pdfatfi.pl /usr/local/bin/| +% \end{quote} +% +% \subsection{Package installation} +% +% \paragraph{Unpacking.} The \xfile{.dtx} file is a self-extracting +% \docstrip\ archive. The files are extracted by running the +% \xfile{.dtx} through \plainTeX: +% \begin{quote} +% \verb|tex ifvtex.dtx| +% \end{quote} +% +% \paragraph{TDS.} Now the different files must be moved into +% the different directories in your installation TDS tree +% (also known as \xfile{texmf} tree): +% \begin{quote} +% \def\t{^^A +% \begin{tabular}{@{}>{\ttfamily}l@{ $\rightarrow$ }>{\ttfamily}l@{}} +% ifvtex.sty & tex/generic/oberdiek/ifvtex.sty\\ +% ifvtex.pdf & doc/latex/oberdiek/ifvtex.pdf\\ +% test/ifvtex-test1.tex & doc/latex/oberdiek/test/ifvtex-test1.tex\\ +% ifvtex.dtx & source/latex/oberdiek/ifvtex.dtx\\ +% \end{tabular}^^A +% }^^A +% \sbox0{\t}^^A +% \ifdim\wd0>\linewidth +% \begingroup +% \advance\linewidth by\leftmargin +% \advance\linewidth by\rightmargin +% \edef\x{\endgroup +% \def\noexpand\lw{\the\linewidth}^^A +% }\x +% \def\lwbox{^^A +% \leavevmode +% \hbox to \linewidth{^^A +% \kern-\leftmargin\relax +% \hss +% \usebox0 +% \hss +% \kern-\rightmargin\relax +% }^^A +% }^^A +% \ifdim\wd0>\lw +% \sbox0{\small\t}^^A +% \ifdim\wd0>\linewidth +% \ifdim\wd0>\lw +% \sbox0{\footnotesize\t}^^A +% \ifdim\wd0>\linewidth +% \ifdim\wd0>\lw +% \sbox0{\scriptsize\t}^^A +% \ifdim\wd0>\linewidth +% \ifdim\wd0>\lw +% \sbox0{\tiny\t}^^A +% \ifdim\wd0>\linewidth +% \lwbox +% \else +% \usebox0 +% \fi +% \else +% \lwbox +% \fi +% \else +% \usebox0 +% \fi +% \else +% \lwbox +% \fi +% \else +% \usebox0 +% \fi +% \else +% \lwbox +% \fi +% \else +% \usebox0 +% \fi +% \else +% \lwbox +% \fi +% \else +% \usebox0 +% \fi +% \end{quote} +% If you have a \xfile{docstrip.cfg} that configures and enables \docstrip's +% TDS installing feature, then some files can already be in the right +% place, see the documentation of \docstrip. +% +% \subsection{Refresh file name databases} +% +% If your \TeX~distribution +% (\teTeX, \mikTeX, \dots) relies on file name databases, you must refresh +% these. 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 intention: +% \begin{quote} +% \verb|latex \let\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}.
