Simple Mach-O header parser for Darwin (macOS X) which dumps some basic information mainly to identify the architecture of the binary.

In order to build and install you have to setup Xcode because it needs a C compiler.

To compile and install you have to call the following make target:

`sudo make install`

Root is needed because it installs to: /usr/local/bin and be sure this directory is in your $PATH variable.

If you just want to compile:

`make all`.

If you don't want to compile you can download the latest release and install/use it on your own.

To dump a binaries header just call:

`modump <path to mach-o binary>` 

Or if you want to dump some executable which is in your path:

`modump $(which <mach-o binary>)`

The generated output should look something like this:

`   file        : /bin/ls
    id          : 0xbebafeca
    header type : fat

        segment #01 at 00000000: __TEXT
        segment #02 at 0x008000: __DATA
        segment #03 at 0x00c000: __LINKEDIT

Fat binaries, which have been compiled for multiple CPUs, always containing two section, each for it's corresponding architecture.
