# Description
# -----------
# Remove the section table from an ELF binary
# so that some tools are blow minded (e.g. gdb)
#
# Example:
# $ python elf_remove_section_table.py /bin/ls ls_without_sections
# $ ls
# elf_remove_section_table.py ls_without_sections
# $ ls_without_sections
# $ elf_remove_section_table.py ls_without_sections
# $ readelf -S ls_without_sections
#
# Il n'y a pas de section dans ce fichier.
# $ gdb ls_without_sections
# "ls_without_sections": not in executable format: File format not recognized
