elfcat - ELF visualizer. Generates HTML files from ELF binaries.

1. How do I install and use it?

       $ cargo install elfcat

       $ elfcat path/to/file

2. What does it look like?

   This is what the following small example ELF file looks like:

   http://ruslashev.github.io/elfcat/hello_world.html

   Steps to create it:

       $ cat hello_world.s

       global _start

       section .text

       _start:

           mov rax, 1

           mov rdi, 1

           mov rsi, msg

           mov rdx, len

           syscall

           mov rax, 60

           xor rdi, rdi

           syscall

       section .data

           msg db "Hello, world!", 0xA

           len equ $ - msg

       $ cat link.ld

       ENTRY(_start)

       SECTIONS {

           . = 0x10080; /* vm.mmap_min_addr + p_offset of first segment */

           .text : {

               * (.text)

           }

           .data : {

               * (.data)

           }

       }

       $ nasm hello_world.s -f elf64

       $ ld hello_world.o -o hello_world -n -T link.ld

       $ elfcat hello_world

       $ xdg-open hello_world.html
