Supysonic looks for two files for its configuration: `/etc/supysonic` and

Supysonic looks for four files for its configuration: `/etc/supysonic`,

`~/.supysonic`, `~/.config/supysonic/supysonic.conf` and `supysonic.conf` in

the current folder, merging values from all files.

Configuration files must respect a structure similar to Windows INI file, with

`[section]` headers and using a `KEY = VALUE` or `KEY: VALUE` syntax.

folder, prefixed by the date of commit that introduced the changes. Those
|

scripts shouldn't be used when initializing a new database, only when
|

upgrading from a previous schema.
|

There could be both SQL scripts or Python scripts. The Python scripts require
|

arguments that are explained when the script is invoked with the `-h` flag.

If a migration script isn't provided for a specific database engine, it simply
|

means that no migration is needed for this engine.
