The following summary is the current status of our sebusybox project.
It shows already ported items and rest of works.
Please tell us, if you know any other extension which should be ported
into busybox.

NOTE: This list is made based on the following description:
      http://selinux.sourceforge.net/devel/userland.php3

NOTE: We don't have a plan to cover libsemanage now, so the related
      commands and features, like setsebool -P option, are not listed
      to be ported.

== SELinux specific commands ==

* We have 32 of SELinux specific commands, and 15 of them should be
  ported into busybox. 9 of them are already merged in the upstreamed
  busybox, and we have rest of 6 items now.

[checkpolicy package] ... 0 of 0 completed
 o /usr/bin/checkmodule
 o /usr/bin/checkpolicy

    so we have no plan to port them.

  - -P option depends on libsemanage, so a limited feature
    version should be ported now.

== SELinux related extensions in the existing commands ==
* We have 40 of SELinux related extensions in the existing commands,
  and 19 of them should be ported into busybox. 12 of them are already
  merged in the upstreamed busybox, and we have rest of 8 items now.

NOTE: Please tell me, if our understanding about these extension
