Dear Zephy development team,

your Getting Started Guide [1] tells at some point to download a SDK, make it
executable, run it:
Run the installation binary, type:

$ chmod +x zephyr-sdk-0.7.2-i686-setup.run

$ sudo ./zephyr-sdk-0.7.2-i686-setup.run

Looking into this file I realized that it contains a big block of binary data.
I'm feeling somehow uncomfortable with just executing a binary from an unknown
source (particular with sudo). Is there another way to install this SDK with
non binary data (I'm willing if build it myself) or to tell me what this SDK
apart from cross-compiler-toolchains contains?

What additional tools apart from a cross-compiler toolchain are required
anyway (and why) for your OS?

Thanks,
Oleg
