## What it is
pyelftools is a pure-Python library with no external dependencies for parsing ELF binaries and DWARF debugging information. It lets Python code inspect executable structure, sections, symbols, and debug metadata.

## Use cases
- parse ELF binary sections and symbols in Python
- extract DWARF debug info from executables
- analyze ELF files without external tools
- inspect binary metadata for security analysis
- build tooling that reads ELF/DWARF programmatically

## When to choose
- you need a dependency-free pure-Python ELF/DWARF parser
- you want to inspect binaries from Python scripts or tools

## When to avoid
- you need to parse non-ELF formats like PE or Mach-O
- you need extremely high-performance binary parsing

## Facets
- artifact type: library
- maturity: stable
- function: parser, developer-tools
- domain: developer-tools, parsers
- platform: python, cross-platform
- tags: elf, dwarf, binary-analysis, pure-python, debugging-info, debugging
