+MaterialX is an open standard for representing rich material and
+look-development content in computer graphics, enabling its
+platform-independent description and exchange across applications
+and renderers.
+Launched at Industrial Light & Magic in 2012, MaterialX has been a key
+technology in their feature films and real-time experiences. The
+project was released as open source in 2017 and MaterialX is a hosted
+project of the Academy Software Foundation since 2021. This standard
+is supported as optional extension by standards and platforms for
+computer graphics, like OpenShadingLanguage and Blender.
+
+MaterialX includes also two graphical interfaces, MaterialX Viewer and 
+MaterialX Graph Editor.
+
+MaterialX Viewer creates the GLSL shaders from MaterialX graphs and
+renders the results using the NanoGUI framework. This framework is not
+available in SBo but is built as third part component of MaterialX.
+The build of internal NanoGUI requires also the buildof robin-map as
+external component. Although this dependency is available in SBo you
+cannot use the one installed in your system. The built does not affect
+other installations of robin-map.
+
+MaterialX Graph Editor can be used to visualize, create, and edit
+MaterialX graphs. It uses the ImGui framework also built as third 
+part component with the headers of an internal GLFW. Although these
+dependencies are available in SBo, the build does not allow the use of
+imgui and glfw3 installed in the system, but the internal components
+built with MaterialX do not conflict with other installations.
+
+By default this slackbuild installs both the graphical interfaces and
+the Python bindings. If not required, you can disable their built by 
+setting the following variables:
+
+VIEWER=no disables the build of MaterialX Viewer. The dependency zenity
+ is not required. You have no even the download of these extrasources:
+ nanogui, nanobind, nanovg, glfw, and robin-map. 
+ 
+EDITOR=no disables the build of MaterialX Graph Editor. The download of
+ following extrasources is not required: imgui and imgui-node-editor.
+ 
+PYTHON=no disables the build of Python bindings. The dependency
+ python3-pybind11 is not required.
+ 
+For example, if you want disable both the graphical interfaces you have
+to launch the script with the following command:
+    VIEWER=no EDITOR=no ./MaterialXViewer.SlackBuild
+ 
+openimageio is an optional dependency autodetected and its support
+will be enable by default if found in the system. If you do not 
+require this extension you can disable it by passing
+    OIIO=no ./MaterialX.SlackBuild

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
