+Sysprof Linux Profiler v. 1.0.8
+
+
+* What is it?
+--------------------------
+
+Sysprof is a sampling system-wide CPU profiler for Linux.
+
+Sysprof uses a Linux kernel module to profile the entire system, not
+just an individual application. Sysprof handles threads and shared
+libraries, and applications do not have to be recompiled or
+instrumented. In fact they don't even have to be restarted.
+
+
+* Features:
+----------------------
+
+    - Profiles all running processes, not just a single application
+
+    - Call graph support showing time spent in each branch of the call tree
+
+    - Has a simple graphical interface
+
+    - Profiles can be loaded and saved
+
+    - Easy to use: Just insert the kernel module and start sysprof
+
+    - Supports Fedora debuginfo packages
+
+
+* Sysprof 1.0.8
+--------------------------
+
+    - Fix panic with preemptive kernels
+
+
+Please report bugs as well as success or failure stories to 
+
+    sandmann@daimi au dk
+
+
+
+* Where can I get it?
