Sharedo is a variant in [[Bash]] of the recursive, general-purpose build tool redo. This variant of redo provides small shell scripts which may be used to construct build systems from small shell scripts. The Bash scripts, and descriptions of how they are used, live in Markdown files which are literate programs. The literate programs are extracted from the Markdown files with the tool lit (which also lives in this repo). I use Obsidian to browse between the Markdown files, so they use the syntax [[README]] to refer to each other.
Credo is an earlier, similar variant of redo, written in the Inferno shell.
