Global help

Install the help binary (DUB config help) onto PATH to open progressive help for any command:

help tar
help --path=/usr/bin/tar tar

Resolution order:

  1. Adjacent help.sdl / help.md / help.adoc / help.cmk (or orientation pack)

  2. OpenShellOrg info TUI or classic info/man

  3. <cmd> --help

Prefer the shell wrapper (prohelp wrapper install) over a bare help binary on PATH for bash/zsh/fish/nu/pwsh. Builtins win over PATH, so only a function named help intercepts reliably. See shell help wrapper docs.

If no adjacent schema exists, prohelp nudges opening a feature request upstream (search link included) before falling back.
