## List EnsDb databases in a MariaDB/MySQL server

### Description

The `listEnsDbs` function lists EnsDb databases in a MariaDB/MySQL server.

### Usage

    listEnsDbs(dbcon, host, port, user, pass)

### Arguments

`dbcon` | A `DBIConnection` object providing access to a MariaDB/MySQL database. Either `dbcon` or all of the other arguments have to be specified.
`host` | Character specifying the host on which the MySQL server is running.
`port` | The port of the MariaDB/MySQL server (usually `3306`).
`user` | The username for the MariaDB/MySQL server.
`pass` | The password for the MariaDB/MySQL server.

### Details

The use of this function requires the `RMariaDB` package to be installed. In addition user credentials to access a MySQL server (with already installed EnsDb databases), or with write access are required. For the latter EnsDb databases can be added with the `useMySQL` method. EnsDb databases in a MariaDB/MySQL server follow the same naming conventions than EnsDb packages, with the exception that the name is all lower case and that each `"."` is replaced by `"_"`.

### Value

A `data.frame` listing the database names, organism name and Ensembl version of the EnsDb databases found on the server.
