/**
Up is a tool to help you manage your developer machine. `up run` runs the tasks defined in its
config directory. It handles linking configuration files into the right locations, and running
scripts to make sure the tools you need are installed and up to date. It is designed to complete
common bootstrapping tasks without dependencies, so you can bootstrap a new machine by:

❯ curl --create-dirs -Lo ~/bin/up https://github.com/gibfahn/up/releases/latest/download/up-$(uname) && chmod +x ~/bin/up

❯ ~/bin/up run --bootstrap --fallback-url https://github.com/gibfahn/dot

Running `up` without a subcommand runs `up run` with no parameters, which is useful for
post-bootstrapping, when you want to just run all your setup steps again, to make sure
everything is installed and up-to-date. For this reason it's important to make your up tasks
idempotent, so they skip if nothing is needed.

There are also a number of libraries built into up, that can be accessed directly as well as via
up task configs, e.g. `up link` to link dotfiles.

For debugging, run with `RUST_LIB_BACKTRACE=1` to show error/panic traces.
Logs from the latest run are available at $TMPDIR/up/logs/up_latest.log by default.
