.SH DESCRIPTION
|
|
.PP
|
|
This is the configuration file used by the account server and other account
|
|
background services, such as; replicator, auditor and reaper.
|
|
|
|
The configuration file follows the python-pastedeploy syntax. The file is divided
|
|
into sections, which are enclosed by square brackets. Each section will contain a
|
|
certain number of key/value parameters which are described later.
|
|
|
|
Any line that begins with a '#' symbol is ignored.

|
|
TCP port the account server should bind to. The default is 6202.
