.SH NAME 
semodule \- Manage SELinux policy modules.

.SH SYNOPSIS
.B semodule [options]... MODE [MODES]...
.br
.SH DESCRIPTION
.PP
semodule is the tool used to manage SELinux policy modules,
including installing, upgrading, listing and removing modules.  
semodule may also be used to force a rebuild of policy from the
module store and/or to force a reload of policy without performing
any other transaction.  semodule acts on module packages created
by semodule_package.  Conventionally, these files have a .pp suffix
(policy package), although this is not mandated in any way.
