+These are the headers for NVIDIA's OptiX ray tracing API. Usage of this
+API allows for an application to offload its ray tracing calculations
+to the system's onboard NVIDIA GPU card, potentially drastically
+render speeds.
+
+Currently, this is only present in the SlackBuilds.org repository as an
+optional dependency for graphics/Blender. If this is installed, the
+graphics/Blender SlackBuild will automatically detect the OptiX headers
+and Blender will be built with support for OptiX, allowing to use it
+for rendering, as well as GPGPU-accelerated image denoising.
+
+This SlackBuild also requires a recent CUDA toolkit (probably newer
+than the current one available in the SBo repository). It will install
+without it, it just will be useless without it.

+# 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 lasat 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.
