## NAME
    [Dpkg::Control::Types](https://www.chedong.com/phpMan.php/perldoc/Dpkg%3A%3AControl%3A%3ATypes/markdown) - export CTRL_* constants

## DESCRIPTION
    You should not use this module directly. Instead you more likely want to use [Dpkg::Control](https://www.chedong.com/phpMan.php/perldoc/Dpkg%3A%3AControl/markdown) which
    also re-exports the same constants.

    This module has been introduced solely to avoid a dependency loop between [Dpkg::Control](https://www.chedong.com/phpMan.php/perldoc/Dpkg%3A%3AControl/markdown) and
    [Dpkg::Control::Fields](https://www.chedong.com/phpMan.php/perldoc/Dpkg%3A%3AControl%3A%3AFields/markdown).

## CHANGES
### Version 0.xx
    This is a private module.
