# Install `mold` official binaries from GitHub Releases.

# Adapted from the official rui314/setup-mold@v1 action to:

# * use environment variables instead of action inputs

# * remove make-default support

# * use curl instead of wget

# * support doas for sudo

# * support redhat systems

# See: https://github.com/rui314/setup-mold/blob/main/action.yml
