When run in this mode, the database is assumed to -be largely uncorrupted. For example, the <a href="../../api_c/db_verify.html">DB->verify</a> method will -search for pages that are no longer linked into the database, and will -output key/data pairs from such pages.

When run in this mode, -the database is assumed to be seriously corrupted. For example, key/data -pairs that have been deleted will re-appear in the output. In addition, -because pages may have been subsequently reused and modified during -normal database operations after the key/data pairs were deleted, it is -not uncommon for apparently corrupted key/data pairs to be output in this -mode, even when there is no corruption in the underlying database. The -output will almost always have to be edited by hand or other means before -the data is ready for reload into another database.
