    The ELF file(s) to analyze. Multiple files can be specified.

The `eu-readelf` command is part of the elfutils package and provides a utility for displaying various information about ELF (Executable and Linkable Format) files. It's similar to `readelf`, but uses the elfutils library, and is designed to be faster and more memory-efficient, especially when dealing with large or numerous ELF files. This command is frequently used by developers, system administrators, and security researchers to examine the structure and contents of executables, shared libraries, object files, and core dumps. `eu-readelf` can extract information such as the ELF header, program headers, section headers, symbol tables, relocation tables, dynamic linking information, debugging information, and more. By inspecting these details, users can understand how a program is structured, how it links to other libraries, where functions and data are located in memory, and what debugging information is available. Its performance advantages make it useful in automated scripting or large-scale analysis scenarios. In summary, `eu-readelf` is a valuable tool for understanding the low-level details of ELF files.

`eu-readelf` aims to provide faster and more memory-efficient analysis of ELF files compared to the standard `readelf` implementation. While the basic functionality is similar, `eu-readelf` may handle certain corner cases or corrupted ELF files differently. Performance is the key area of improvement.

The `eu-readelf` command exits with a status of 0 if it successfully processes all specified files. It exits with a non-zero status if any errors occur during file processing or if invalid options are provided.
