+GLXOSD, an OSD and benchmarking tool for Linux
+
+GLXOSD is an on-screen display (OSD)/overlay for OpenGL applications running on Linux with X11.
+It can show FPS, the temperature of your CPU, and if you have an NVIDIA graphics card (with proprietary drivers)
+it will also show the temperature of the GPU. Also, it can log frame timings, which is useful for benchmarking.

+# 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.
