Finally, sRGB output is still possible. However, the color processing used in this case
is fairly na\"ive: out-of-gamut values are simply clipped. This is something that may
be improved in the future (e.g. by making use of a color management library like \code{lcms2})
\subsection{Using Mitsuba from Makefiles}
Sometimes it is useful to run \code{mitsuba} from a standard Unix Makefile. This is a bit inconvenient because shell commands in Makefiles are executed using the
classic \code{sh} shell, which is incompatible with the \code{setpath.sh} script.
A simple workaround in this case is to explicitly call \code{bash} or \code{zsh}, e.g.
\begin{shell}
MITSUBA_HOME=$\langle$..$\rangle$
%.exr: %.xml
bash -c ". $\texttt{\$}$(MITSUBA_HOME)/setpath.sh; mitsuba -o $\texttt{\$}$@ $\texttt{\$}$<"
\end{shell}
