# This file `obj.txt` is a hexdump with comments to manually build an ELF file.
# Lines starting with '#' are comments.
# The rest is read as per `xxd -r -p` (see `man xxd`)
# You can build the binary executable `obj.elf` using the command:
# ```bash
# <obj.txt grep -v '^#' | xxd -r -p >obj.elf
# ```
# You can then use chmod to make `obj.elf` executable.
