mkhistory - rebuild news history file
/usr/lib/news/maint/mkhistory [ -s sizemultiplier ]
Mkhistory rebuilds the history file and its auxiliaries to match the
articles in /var/spool/news. Normally mkhistory uses a reasonable
default size for the dbz(3Z) index database; if the -s option is given,
the expected number of entries in the history database is taken to be
the number of articles found in /var/spool/news times sizemultiplier.
Mkhistory is fairly slow and locks the whole news system for the
duration of the run, so it should not be run casually.

Mkhistory is inherently incapable of reconstructing history-file lines
corresponding to expired articles. Protection against old articles
reappearing is thus somewhat limited for a while after the history file
