.SH NAME
.LP
.B object-expirer.conf
\- configuration file for the openstack-swift object exprier daemon
.SH SYNOPSIS
.LP
.B object-expirer.conf
.SH DESCRIPTION
.PP
This is the configuration file used by the object expirer daemon. The daemon's
function is to query the internal hidden expiring_objects_account to discover
objects that need to be deleted and to then delete them.
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.
You can find more information about python-pastedeploy configuration format at
\fIhttp://pythonpaste.org/deploy/#config-format\fR
