Essentially, yes. htdig will tag pages for deletion when it gets a
404 error for them or the host address of the server no longer exists,
and htmerge will actually delete these pages if the remove_bad_urls
attribute is true (which it is by default). However, apart from that
there's no easy way of instructing it to delete individual pages, or
all the pages for a particular site. The 3.2 release will include a
utility for doing just this.
For 3.1.x, the best way to clean up your database is to reindex from
scratch using htdig -i. You can still run this with -a if you want,
and move the .work files over top of the non-.work files afterward.
