+  3D-ICE stands for 3D Interlayer Cooling Emulator. It is a
+Linux-based Thermal Emulator Library written in C, which can perform
+transient thermal analyses of vertically stacked 3D integrated
+circuits with inter-tier Microchannel Liquid Cooling. The latest
+version, namely 3D-ICE 3.1, supports fully customized non-uniform
+thermal modeling and different heat sink models.
+
+
+  If you want to enable the SystemC wrapper, set the environment
+variable SYSTEMC=yes.

+# 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.
