NexTrieve

Changes for version 0.31

Refined the internal "_resync_news" method to quickly handle "holes" in the message stream. Now also uses a binary chop approach to find the last message that's on the news server that is already in the targz. This all applies to Targz.pm of course.
24 March 2002 Added and documented method "add_news" to Targz.pm. Takes a Net::NNTP object and reads messages from there, adding them to the targz. Handles re-syncing with newsgroups by a mix of date and message-id checks.
Added and documented method "name" to Targz.pm. Added and documented method "count_storable", which is the same as "count" but uses the Storable module for persistency to prevent having to unpack tarfiles that haven't changed. Added checks to test-suite.
Modified internal method "auto_clean" to "no_auto_clean" and documented it. Modified internal method "clean" to only work as an object method and documented it. Both in Targz.pm.
Simplified some internals in Targz.pm. The tar program must now also be able to handle the "--directory" directive.
23 March 2002 Added and documented a "tarfile" method to Targz.pm.
Made the datestamp checking routine in Targz.pm a little smarter so that it now also recognizes and handles NNTP-Posting-Date: and X-Trace: headers.
Added support for an external hash to "count" method of Targz.pm: using an external hash can make things a lot faster because it does not need to read tar-files that haven't changed.
Made directory parameter to Targz method of NexTrieve.pm default to the current directory.
22 March 2002 Adapted the undocumented "files" method of Docseq.pm so that it can accept a processor routine parameter. Also documented the method now. It is now useful as a basic conversion feature for any type of conversion by other modules.
