# Gitea Actions – Sync git repository to SVN
# Equivalent of .circleci/config.yml, translated to GitHub Actions syntax
# which Gitea Actions supports natively.
#
# Prerequisites (set as repository Secrets in Gitea → Settings → Secrets):
#   SVN_USERNAME  – SVN commit username
#   SVN_PASSWORD  – SVN commit password
#   SVN_REPO_URL  – Base SVN repo URL (e.g. https://svn.example.com/repos/myproject)
