+MangoHud is a Vulkan and OpenGL overlay for monitoring FPS,
+temperatures, CPU/GPU load and more.
+
+MangoHud may be built with access to Nvidia's NV_Control X
+extension. This introduces a dependency on libxnvctrl and
+may be included by passing XNVCTRL=enabled.
+
+By default, MangoHud reaches out to the internet to pull
+Vulkan-Headers. Since Slackware ships with vulkan-sdk, we
+enable system headers by default. To disable this feature
+and restore default behavior, pass SYSVULKAN=disabled to
+the build script.

+# 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.
