+Unigine Superposition is an extreme performance and stability test
+for PC hardware: video card, power supply, cooling system. Check
+your rig in stock and overclocking modes with real-life load! Also
+includes interactive experience in a beautiful, detailed environment.
+
+Please note that the source file is 1500mb if you are on a slow
+internet connection.  And building the package will take several 
+minutes due to its large size. 
+
+Unigine Superposition is 64-bit only.  It will not run on 32-bit
+Slackware.

+# 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 ':'.
