# [afpedit] Module Configuration

The `afpedit` module allows you to manage the AFP databases, including adding and removing tracks, optimizing the database, and retrieving information on the contents of the database.

## Input and Output

The `afpedit` module has four modes of operation.

Mode | Input | Output | Description
--- | --- | --- | ---
`FINGERPRINT_ADD` | `af` |  | Receives AFP feature data, and adds it to the database under the specified track identification tag.
`FINGERPRINT_REMOVE` |  |  | Removes entries from the database associated with the specified track identification tag.
`FINGERPRINT_OPTIMIZE` |  |  | Optimizes the database’s internal indexes. You must use this mode periodically between adding and removing tracks.
`FINGERPRINT_INFO` |  |  | Generates a list of the database’s contents.

Examples:

    output <- afpedit(FINGERPRINT_ADD,fp)

    output <- afpedit(FINGERPRINT_ADD,fp)

## Parameters

Some of these parameters do not have an internal default value. You must either set the configuration parameter to a suitable value, or set the value in the corresponding action parameter.
