+We build all the tools into a single virt-mem executable, in order to
+share the most runtime. Almost all the code between individual tools
+is shared anyway.
+
+lib/
+
+ - The common core of all the tools. Library, kernel symbols, command
+ line handling, memory images, etc.
+
+uname/
+dmesg/
+ etc.
+
+ - The code specific to each tool, usually rather small.
+
+mem/
+
+ - This brings everything together and links it into a single executable.
+ Other than that purpose, there is almost nothing in this directory.
