I would like to take a moment of your time, and point you to a little
bit of software that I've been working on recently.
I am not sure if this list is exclusive to Laurent Bercot's software,
but given that my project uses skalibs and the overall appreciation of
djb software here I thought you might be interested anyway.

What I have been working on is an implementation of djb's redo, which I
have dubbed 'credo' (because it's implemented in C, you know?)


djb's design notes for redo have existed for quite a while now,
unfortunatly he never released the program itself.
This led to several implementations of it. However all of them seem to
have been abandoned somewhere along the way for reasons unknown to me.
So I decided to explore this topic myself.

redo is a build-system best comparable to the classic 'make' found on
just about any UNIX there is.
Unlike make however redo is very simple in it's design.
I have to admit that documentation is a little scarce at this point. On
the other hand due to redo's simplicity you don't have to read through
megabytes of html, because there just is no arcane syntax to
understand in the first place.
redo is just plain sh with 3 parameters and it's stdout redirected to
your build target. (in fact sh is just the default - you can use
whatever language you like to write build-scripts)
I believe djb's notes and the *.do scripts in the credo repository
should be enough to get you started.

credo is currently in a v0.x stage. That means some mallocs still go
unchecked, because at the moment I'm mostly concerned with getting the
things right that djb left open, most notably the way build-dependencies
are stored.
That said, I am using credo for a few other projects of mine, including
a Java and some LaTeX projects and of course credo itself.
Therefore I think credo is now ready for an educated audience.

I'm interested in any kind of feedback, but I'm hoping to get some
feedback with regard to the compatibility with systems other than linux.
