Usage: isabelle sync_repos [OPTIONS] TARGET

  Options are:
    -A ROOT      include AFP with given root directory (":" for """ + AFP.BASE.implode + """)
    -J           preserve *.jar files
    -S           robust (but less portable) treatment of spaces in directory names
    -T           thorough treatment of file content and directory times
    -a REV       explicit AFP revision (default: state of working directory)
    -n           no changes: dry-run
    -r REV       explicit revision (default: state of working directory)
    -p PORT      explicit SSH port (default: """ + SSH.default_port + """)
    -v           verbose
