+\section{Building the HTML Manual for Context Help}%

+
+In addition to compiling your own \CGG{}, you should also build an html version of the manual that is needed for Context Help in the program. The main version of the manual is in latex to produce a pdf version of the manual and this is required to be built first as the basis for the html version. This means that you need a full latex environment, git, and the latex2html program in order to eventually create the html version. Texlive is about 1 GB; Latex2html itself has many requirements and missing any will result in failure: some requirments include Netpbm, GhostScript, dvips, etc. Latex2html must be at least version \textit{2021.2} in order to create the html manual version from the latex.
+
+The steps are as follows:
+\begin{enumerate}
+ \item Download the manual in LaTeX:
+
+\begin{lstlisting}[style=sh]
+git clone "git://git.cinelerra-gg.org/goodguy/cin-manual-latex.git" master
+\end{lstlisting}
+
+ \item Included in the download is the \texttt{translate\_manual} script. After modifying this file to have execute permission, run this script from a terminal window in the \textit{master} directory where it was downloaded (be aware that this script includes several \textit{rm} commands):
+\begin{lstlisting}[style=sh]
+./translate_manual
+\end{lstlisting}
+
+ The steps that this script performs are as follows:
+ \begin{itemize}
+ \item PDF production. The PDF document will be produced from the latex source in the \textit{master} directory. Since the glossary and index are also present, it has to run the pdf build several times. The following commands in the \texttt{translate\_manual} script produce the PDF document from latex source which includes invoking makeindex for the Index and Glossary.
+
+ \begin{lstlisting}[style=sh]
+ pdflatex CinelerraGG_Manual.tex
+ makeindex CinelerraGG_Manual.idx
+ pdflatex CinelerraGG_Manual.tex
+ makeindex CinelerraGG_Manual.nlo -s nomencl.ist -o CinelerraGG_Manual.nls
+ pdflatex CinelerraGG_Manual.tex
+ \end{lstlisting}
+
+ After these commands are executed you will have the manual only in PDF format. So if you only want a PDF version, you only need to run these previous 5 lines but Context Help from the program will not be available with the PDF version.
+ \item Next, to produce HTML output the script then moves (renames) \texttt{latex 2html-init} to \texttt{.latex2html-init} (starting with dot).
+
+ \item Then the script uses latex2html: latex2html is run with a unique set of parameters and some cleanup is performed. It creates the directory CinelerraGG\_Manual containing all the files of the manual in html: tables, references, index, glossary, and various images.
+ \end{itemize}
+
+ \item After installation of the \CGG{} program, place the complete unchanged directory \texttt{CinelerraGG\_Manual}, as it was produced by latex2html from the manual package, into the \textit{doc} directory of the installed Cinelerra package. This will be the directory \textit{bin/doc/CinelerraGG\_Manual} if \CGG{} was built \texttt{--with-single-user}. The script ContextManual.pl will automatically be in bin/doc after the successful build of the program. It is this perl script that allows the program to access CinelerraGG\_Manual to offer Context Help.
+
+ \item Optionally you can make some adjustments to the latex2html command line in the \texttt{translate\_manual} script. Some variants are shown in the comments inside the script but changes may impact the usability of Alt/h hotkey from the program.
