I can offer this (warning, crufty real-world scripts ahead!): these make files and bash script (https://github.com/simonmichael/hledger/blob/137d825/Makefile https://github.com/simonmichael/hledger/blob/137d825/Makefil..., https://github.com/simonmichael/hledger/blob/137d825/Makefile.helpsys https://github.com/simonmichael/hledger/blob/137d825/Makefil..., https://github.com/simonmichael/hledger/blob/a3c300b/bake https://github.com/simonmichael/hledger/blob/a3c300b/bake) were replaced by this roughly equivalent Justfile (https://github.com/simonmichael/hledger/blob/137d825/Justfile https://github.com/simonmichael/hledger/blob/137d825/Justfil...) (some old things were commented out, some new things were added). I'm only a few weeks in, and just has its own learning curve, but I'm very pleased overall. Cognitive load is down, usability is up, robustness is up. ("After many years with make and plain shell ... for scripting, just is better enough, and the goal of clean consolidated efficient project automation is so valuable, that I am relying on it even though it's not installed by default.")
