developer is officially maintaining the package.
The rationale for changing this from "tech-pkg" to "pkgsrc-users" is
that it implies that any user can try to maintain the package (by
submitting patches to the mailing list). Since the folks most likely
to care about the package are the folks that want to use it or are
already using it, this would leverage the energy of users who aren't
developers.
Valgrind is a suite of tools 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 speed up and reduce memory use of your programs.
The Valgrind distribution currently includes five tools: two memory error
detectors, a thread error detector, a cache profiler and a heap profiler.
