-This storage manager attempts to implement the 'traditional' INN storage
-layout, i.e a message crossposted to alt.fan.james-brister and rec.pets.wombats
-will be written as a file in
-       <patharticles>/alt/fan/james-brister/nnnnn
-and a symlink pointing to the above file in
-       <patharticles>/rec/pets/wombats/mmmmmm
-where nnnnn and mmmmmm are the article numbers that article has in each of 
-those two newsgroups.  (Actually in the traditional spool form the link
-could be either a symlink or a regular link).
-
-The storage token data for a tradspool stored article is a 16-byte block.
-The storage token contains two ints; the first one is a number
-telling what the name of the "primary" newsgroup is for this article, the
-second one telling what article number the article has in that newsgroup.
-The mapping between newsgroup name and number is given by a database in
-the file
-       <pathspool>/ts.ng.db
-; this file is a straight ASCII file listing newsgroup names and
-numbers, and will be automatically generated by innd if one does not
-exist already.  This database is read in automatically by any program
-that uses this storage manager module, and is updated by innd whenever
-a new newsgroup is encountered.  Other programs (like innfeed) check
-the mod time of that database every 5 minutes to see if they need to
-recheck it for any new newsgroups that might have been added.  Should
-the database become corrupted, simply shutting down news, removing the
-database, and doing a makehistory will recreate the database.  It
-should, in principle, be possible to write a perl script to recreate
-just the database from just the spool files and history files without
-doing a full makehistory. 
-
-Currently the storage manager code works, although not perhaps as fast 
-as it could.   The expiration code is somewhat unwieldy; since the storage
-token does not have enough space to hold all the newsgroups an article 
-is posted to, when expiration is done SMCancel() has to open the article
-to find out what other newsgroups the article is posted to.  Eurggh. 
-Suggestions for a better scheme are welcome. 
-
-Other problems of note: the storage manager code has no way to get to the 
-'DoLinks' (-L) flag setting of innd, so currently you can't use the
-"crosspost" program with tradspool.  I guess the proper thing to do would be
-to make DoLinks a config option in storage.conf instead, but I haven't
-done that yet.
