.TH CHECKMODULE 8
.SH NAME
checkmodule \- SELinux policy module compiler
.SH SYNOPSIS
.B checkmodule
.I "[-b] [-m] [-M] [-V] [-o output_file] [input_file]"
.SH "DESCRIPTION"
This manual page describes the
.BR checkmodule
command.
.PP
.B checkmodule
is a program that checks and compiles a SELinux security policy module
into a binary representation.  It can generate either a base policy
module (default) or a non-base policy module (-m option); typically,
you would build a non-base policy module to add to an existing module
store that already has a base module provided by the base policy.  Use
semodule_package to combine this module with its optional file
contexts to create a policy package, and then use semodule to install
the module package into the module store and load the resulting policy.

.SH OPTIONS
.TP
.B \-b
Read an existing binary policy module file rather than a source policy
module file.  This option is a development/debugging aid.
.TP
.B \-m
Generate a non-base policy module.
.TP
.B \-M
Enable the MLS/MCS support when checking and compiling the policy module.
.TP
.B \-V
 Show policy versions created by this program
.TP
.B \-o filename
Write a binary policy module file to the specified filename.
Otherwise, checkmodule will only check the syntax of the module source file
and will not generate a binary module at all.

.SH EXAMPLE
.nf
# Build a MLS/MCS-enabled non-base policy module.
$ checkmodule -M -m httpd.te -o httpd.mod
.fi
