# SimpiCI provider for [@Author::GETTY] distributions.
#
# SimpiCI runs this image once, read-only over the checkout, with a private
# writable directory at $CICD_PROVIDER_OUT. We write one `.sh` job file per
# supported Perl version into $CICD_PROVIDER_OUT; SimpiCI merges them into the
# staging .cicd WITHOUT overwriting a repository's own files, so a dist that
# ships its own `perl+5.40+test.sh` keeps it. We receive no registry
# credentials and no Docker socket by design.
#
# The generated jobs run LATER, each in a `perl:<ver>` container, with the
# checkout read-only at /workspace and the staging dir read-only at /cicd
# (CICD_ROOT=/cicd). They source the shared helper we also drop in lib/.

# Debian release the oldest perl:<ver> images no longer serve packages for), else
# the per-run SIMPICI_PROVIDER_PERL_VERSIONS override, else the baked-in default.
# `#` starts a comment; whitespace and newlines separate versions.
