Thanks. I still can&#x27;t believe that my little hack of a makefile became so popular ;-). I wish my other personal projects grew as popular as it. It started as personal &quot;executable documentation&quot; to keep sanity in the early days of esp8266 hacking, where there were lot of duplication and big binary blobs flying around (VMs, binary toolchains of questionable licensing). All the real kudos go to @jcmvbkbc who quickly implemented esp8266 support in GCC and maintains it well since then. My little project just makes his and other work accessible to almost everyone who can type few commands in a terminal, with as much as possible build from source (and thus available for tweaking). And the fact that it became popular means that OpenSource is not just an empty motto.
