alembic 1.4.3-1ubuntu1 (amd64 binary) in ubuntu impish

 Alembic is a new database migration tool, written by the author
 of SQLAlchemy. A migration tool offers the following functionality:
 .
  * Can emit ALTER statements to a database in order to change the
    structure of tables and other constructs
  * Provides a system whereby "migration scripts" may be constructed;
    each script indicates a particular series of steps that can
    "upgrade" a target database to a new version, and optionally a
    series of steps that can "downgrade" similarly, doing the same
    steps in reverse.
  * Allows the scripts to execute in some sequential manner.
 .
 This package provides /usr/bin/alembic script and documentation for Alembic,
 and depends on the python3-alembic package which contains all the actual code
 (in Python 3) for Alembic to actually work.
