[catenate]

Inspired somewhat by redo, I wrote "credo" as a set of small command-line build tools, so build description files are in the shell language rather than a standalone DSL.

(I don't like how makefiles have so many features that reimplement what you can do in the shell. I also don't care for big languages with build-tool DSLs--though you could say credo is a build-tool DSL for the shell, like git is a version-control DSL for the shell. With only language directives, no constructs.)

I wrote it in the Inferno shell to take advantage of some nice OS features and its cleaner shell language. One of these days I should port it to bash, so other people might use it.
