%description
BCC is a toolkit for creating efficient kernel tracing and manipulation
programs, and includes several useful tools and examples. It makes use of
extended BPF (Berkeley Packet Filters), formally known as eBPF, a new feature
that was first added to Linux 3.15. BCC makes BPF programs easier to write,
with kernel instrumentation in C (and includes a C wrapper around LLVM), and
front-ends in Python and lua. It is suited for many tasks, including
performance analysis and network traffic control.
