The Mark One build system is probably not a build system at all: it's just a script you run which produces whatever output files you need. Maybe it does some manual out of date checks but it possibly just blurts out all the generate calls regardless.
#!/bin/fish # an example of a Mk1 build system pandoc -t gfm README.md -f html -o README.html
This is just a script. It has no abstract knowledge of out of date, dependencies, parallel execution and the like. You have to specifically tell it how to do literally everything.
