SUMMARY = "A utility to print stack traces of running processes"
DESCRIPTION = "A from-scratch implementation of pstack using DWARF debugging and unwind information. \
Works for C/C++, Go, Rust, and Python. A traditional pstack command can generally print a backtrace \
of each thread in a running program, and sometimes from a core file. This version of pstack uses its \
own self contained ELF and DWARF parsing library, libdwelf to parse the DWARF debug and unwind \
information, to get a stack trace."
