dd Z dS )ModuleCompilerat ModuleCompiler eases running of the module compiler.
The ModuleCompiler class encapsulates running the commandline
module compiler (checkmodule) and module packager (semodule_package).
You are likely interested in the create_module_package method.
Several options are controlled via paramaters (only effects the
non-refpol builds):
.mls [boolean] Generate an MLS module (by passed -M to
checkmodule). True to generate an MLS module, false
otherwise.
.module [boolean] Generate a module instead of a base module.
True to generate a module, false to generate a base.
.checkmodule [string] Fully qualified path to the module compiler.
Default is /usr/bin/checkmodule.
.semodule_package [string] Fully qualified path to the module
packager. Defaults to /usr/bin/semodule_package.
.output [file object] File object used to write verbose
output of the compililation and packaging process.

a source file name. The source file must be in the form
of "foo.te". This will generate "foo.mod" and "foo.pp".

sourcename.
The create_module_package creates a module package saved in a
file named sourcename (.pp is the standard extension) from a
source file (.te is the standard extension). The source file
should contain SELinux policy statements appropriate for a
base or non-base module (depending on the setting of .module).
Only file names are accepted, not open file objects or
descriptors because the command line SELinux tools are used.
On error a RuntimeError will be raised with a descriptive
error message.
