 * Add more functions used by ported packages (check openssh).
+* Add more unit tests.
 * Add missing man pages.

+  - timeconv?
 * Add a README.import file.
+* Update man pages:
+  - Fix references to a.out(5) and inline needed struct definitions.
+  - Document when each interface was added on every BSD, and libbsd.
+* Handle LFS properly. By default the library emits LFS objects, but might

+  _LARGEFILE_SOURCE and _LARGEFILE64_SOURCE. Or error out when the off_t
