Technically speaking it is a very large configuration file. The config reader runs Ribosome 0.8, which escaped from the lab a couple of billion years ago and infested a whole planet to the point that it became inhospitable to life.
You left out the preprocesser (RNA transcriptase) which takes the config file and transcribes it, possible modifying some bits in-place, before it gets to the ribosome.
#defines all over the place as well as decidedly unhygienic macros. Serves them right for still using 'C'. The list of CVEs is endless for that stuff, entire encyclopedias full of them.
