\subsection{Creating a ParaView Catalyst Edition}
The main operations for creating an edition of Catalyst are:
\item Choose one or more editions to be the basis of the new one [optional]
\item Set CMake build parameters (e.g. static or shared library build).
\item Specify files from the ParaView source tree to be copied into the created Catalyst source tree.

\subsection{Customizing editions}
Whereas creating a new edition from scratch may be quite complex, it is possible to extend
an existing edition and customize it. In order to properly separate the work, the customized part
of the edition has its own manifest.json file, that explicitly specifies which other editions are
"edition": "Custom",
"requires": [
In this case, a "Base" edition and an "Enable-Python" edition must be provided when exporting
the Custom edition. The script will first process the "Base" configuration, then the "Enable-Python"
configuration and finally the "Custom" one. This allows an incremental workflow for creating editions.
Note that the \emph{-i} in command line options must be ordered, required editions appear first:
python -r <paraview_sources> -i Path/to/Base -i Path/to/Enable-Python \
-i Path/to/Custom -o <Catalyst_source_dir>
\subsection{Setting CMake Build Parameters}
By default, Catalyst will be built with the default ParaView build parameters (e.g. build with
shared libraries) unless one of the Catalyst editions changes that in its manifest.json file. An

\subsection{Creating an Edition}
Some Catalyst Editions are included in the ParaView source code, under the Catalyst/Editions directory.
They can be used directly, or be included in a custom edition, or be modified.
The official ParaView download page provides a section with different Catalyst source code.
These sources were extracted from ParaView using combinations of the following editions:
\item[Base] \hfill \\
The base of all editions. Various CMake options are set to off in order to minimize dependencies,
such as \mbox{PARAVIEW\_BUILD\_QT\_GUI} and \mbox{PARAVIEW\_ENABLE\_PYTHON}.
If the core modules are extracted (as vtkPVClientServerCoreCore), there is only a few filters
(as the Append, AppendMolecule and AppendPolyData filters, needed to merge data from different MPI ranks).
\item[Enable-Python] \hfill \\
An edition to enable python wrapping. Necessary to use python pipelines.
\item[Essentials] \hfill \\
The main filters (including Clip and Contour). Note that it contains the PVTrivialProducer,
needed to add data in the pipeline. Requires Base.
\item[Extras] \hfill \\
Writers and more filters. Requires Essentials.
\item[Rendering-Base] \hfill \\
A good base to use rendering features. This edition enables screenshots,
and allows to use views and representations.
Requires Extras.
\item[Rendering-Base-Python] \hfill \\
