parted-1.5.6-alt2 provides not so much documentation, although there are various useful and up-to-date docs in doc/ sibdirectory of the sources.
So I suggest to include FAQ, USER (manual) etc. (even the FAT file because it can be useful to someone) to the parted package, API to libparted-devel.
BTW 1.6.0 is out.
to maintainer; seems fixed? :-)
fixed in parted-1.6.12-alt1
