What is elffile?

ELF (Executable and Linkable Format) is a standard file format for executable files, object code, shared libraries, and core dumps in Unix and Unix-like operating systems. The ELF file format is used in various Unix-based operating systems like Linux, Solaris, and macOS.

Some key features of ELF files include:

• ELF files contain information about program sections, symbols, and relocation instructions.
• ELF files can be either statically linked (where all library code is copied into the executable) or dynamically linked (where the program relies on shared libraries).
• ELF files can contain debugging information, which can be useful for troubleshooting or performance profiling.
• ELF files support multiple architectures, so a single file can be executed on different types of hardware.

ELF files are an important part of the Unix software ecosystem, and are used extensively in many open-source projects.
