esptool is a tool to allow the creation and handling of firmware
files suitable for the ESP8266 chip.
It can read a code file in the ELF format that the compilers produce.
From there it is possible to extract various sections that are present
in these files, to either directly dump a section to a file or to
assemble a firmware file comprised of several segments.
While the codebase implements many functions, only a few are used
by the program currently. The program interprets the arguments
given on the commandline, and in the order they are given.
