I often hear people saying "all build-systems suck", an opinion I have been sharing for years, and this is the motivation for this project. I finally got the opportunity to make it open-source, and here it is.
In a few words, it is like make, except it can be comfortably used even in big projects using HPC (with millions of jobs, thousands of them running in parallel).
The major differences are that: - dependencies are automatically tracked (no need to call gcc -M and the like, no need to be tailored to any specific tool, it just works) by spying disk activity - it is reliable : any modification is tracked, whether it is in sources, included files, rule recipe, ... - it implements early cut-off, i.e. it tracks checksums, not dates - it is fully traceable (you can navigate in the dependency DAG, get explanations for decisions, etc.)
And it is very light weight.
Configuration (Makefile) is written in Python and rules are regexpr based (a generalization of make's pattern rules).
And many more features to make it usable even in awkward cases as is common when using, e.g., EDA tools.
Give it a try and enjoy :-)
