NAME         top

       semodule_expand - Expand a SELinux policy module package.

SYNOPSIS         top

       semodule_expand [-ahV] [ -c [version]] basemodpkg outputfile

DESCRIPTION         top

       semodule_expand is a developer tool for manually expanding a base
       policy module package into a kernel binary policy file.  This tool
       is not necessary for normal operation of SELinux.  In normal
       operation, such expanding is performed internally by libsemanage
       in response to semodule commands.  Base policy module packages can
       be created directly by semodule_package or by semodule_link (when
       linking together a set of packages into a single package).

OPTIONS         top

       -h     show help

       -V     show version

       -c [version]
              policy version to create

       -a     Do not check assertions.  This will cause the policy to not
              check any neverallow rules.
