-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 flexible tool for debugging and profiling Linux-x86
+executables. The tool consists of a core, which provides a synthetic
+x86 CPU in software, and a series of "skins", each of which is a
+debugging or profiling tool. The architecture is modular, so that new
+skins can be created easily and without disturbing the existing
+structure.
+
+A number of useful skins are supplied as standard. In summary, these
+are:
+- The memcheck skin detects memory-management problems in your
+ programs,
+- cachegrind performs detailed simulation of the I1, D1 and L2 caches
+ in your CPU and so can accurately pinpoint the sources of cache misses
+ in your code,
+- addrcheck skin is a lightweight version of memcheck,
+- helgrind is designed to find data races in multithreaded programs.

+Valgrind jest elastycznym narzêdziem s³u¿±cym do odpluskwiania i
+profilowania programów pod Linuksem. Sk³ada siê z rdzenia
+dostarczaj±cego syntetyczny emulowany procesor zgodny z x86 i ze
+"skórek" bêd±cych narzêdziami o ró¿nych zastosowaniach. Architektura
+programu jest modularna, wobec czego ³atwo mo¿na stworzyæ nowe skórki
+nie ryzykuj±c popsucia reszty.
+
+Standardowo dostarczone jest kilka u¿ytecznych skórek:
+- memcheck wykrywa problemy z zarz±dzaniem pamiêci± w programach,
+- cachegrind przeprowadza symulacjê pamiêci cache procesora w celu
+ znalezienia miejsc, w których cache zawodzi,
+- addrcheck jest lekk± wersj± memchecka,
+- helgrind wykrywa konflikty dostêpu w wielow±tkowych programach.
