-Valgrind is a GPL'd tool to help you find memory-management problems
-in your programs. When a program is run under Valgrind's supervision,
-all reads and writes of memory are checked, and calls to
-malloc/new/free/delete are intercepted. As a result, Valgrind can
-detect problems such as:
-
-- Use of uninitialised memory
-- Reading/writing memory after it has been free'd
-- Reading/writing off the end of malloc'd blocks
-- Reading/writing inappropriate areas on the stack
-- Memory leaks -- where pointers to malloc'd blocks are lost forever
-- Passing of uninitialised and/or unaddressible memory to system calls
-- Mismatched use of malloc/new/new [] vs free/delete/delete []
-- Some misuses of the POSIX pthreads API
+Valgrind is a GPL'd system for debugging and profiling x86-Linux
+programs. With the tools that come with Valgrind, you can
+automatically detect many memory management and threading bugs,
+avoiding hours of frustrating bug-hunting, making your programs more
+stable. You can also perform detailed profiling to help speed up your
+programs.
