README

        
This git repo is about doing a DDC POC - a proof-of-concept of a [diverse double compilation](https://www.schneier.com/blog/archives/2006/01/countering_trus.html) using tinycc aka tcc because

* it is easier to get started with it

* it is already building reproducibly

* faster to compile (gcc takes over one hour)

* it has fewer build dependencies (which need to be version-tracked when rebuilding)

## Using more compilers

`ddc.sh` will automatically pick up the following compilers on your PATH and

test them:
