"""
dbwire - minimal, dependency-free (stdlib-only) database wire-protocol clients used as a fallback for
sqlmap's direct ('-d') connection when no native driver (and no SQLAlchemy) is installed.

Design note: connectors speak a *wire protocol*, not a product, so a single client covers the whole
compatible family - e.g. the PostgreSQL client also serves CockroachDB, CrateDB, Redshift and Greenplum;
a MySQL client serves MariaDB/TiDB/Aurora; a TDS client serves MSSQL/Sybase. Each module exposes a small
PEP 249 (DB-API 2.0) subset (connect(), Connection.cursor()/commit()/close(), Cursor.execute()/fetchall()).
