* @defgroup purge Package purging functions
|
|
*
|
|
* These functions will purge an specified package or all packages.
|
|
* Only packages in XBPS_PKG_STATE_CONFIG_FILES state will be processed
|
|
* (unless overriden). Package purging steps:
|
|
*
|
|
* - Unmodified configuration files will be removed.
|
|
* - The purge action in the REMOVE script will be executed (if found).
|
|
* - Metadata files will be removed and package will be unregistered
|
|
* with xbps_unregister_pkg().
