-\label{sub:command_line_rendering}
-\index{rendering!command line}
-
-The command line rendering method consists of a way to load the
-current set of batch rendering jobs and process them without a
-GUI\@. This is useful if you want to do rendering on the other side
-of a low bandwidth network and you have access to a high powered
-computer located elsewhere. Setting up all the parameters for this
-operation is somewhat difficult. That is why the command line aborts
-if any output files already exist.
-
-To perform rendering from the command line, first run \CGG{} in
-graphical mode. Go to \texttt{File $\rightarrow$ Batch
- Render}. Create the batches you intend to render in the batch window
-and close the window. This saves the batches in a file. Set up the
-desired render farm attributes in \texttt{Settings $\rightarrow$
- Preferences} and quit out of \CGG{} if you want to use the Render
-Farm capability. These settings are used the next time command line
-rendering is used to process the current set of batch jobs without a
-GUI\@.
-
-On the command line run:
-
-\begin{lstlisting}[style=sh]
-cin -r
-\end{lstlisting}
+\texttt{batchjob.rc}. \textbf{Warning} this file will be modified
+so if you use any filename that is not a legitimate list of batch jobs to
+render, that file will be overwritten and its previous contents destroyed.
+When invoked with these parameters, \CGG{}
+will start up and perform the rendering jobs in the list contained
+in that file, without creating its usual windows. If you do not
+specify a filename, the default will be \$HOME/.bcast5/batchrender.rc.
+Possible messages you might see where you started up the job are as follows.
+\begin{description}
+\item[The following files exist: - filename - Won't overwrite existing files] that batch job will not run in order to prevent writing over previous run.
+\item["filename" No such file or directory] the specified batch job file does not exist.
+\item["filename": Permission denied] the specified batch job file does not have write permission so can not be updated.
+\item[Render::run: filename] the batch job with the name of filename will be processed.
+\item[** rendered 0 frames in 0.000 secs, 0.000 fps] either you used a file that is not a list of batch jobs or the batch jobs within the file were not enabled.
