## First line gives history retention; other lines specify expiration

## <modflag> Pick one of M U A -- modifies pattern to be only
## moderated, unmoderated, or all groups
## <keep> Mininum number of days to keep article
## <default> Default number of days to keep the article
## <purge> Flush article after this many days
## <keep>, <default>, and <purge> can be floating-point numbers or the
## word "never." Times are based on when received unless -p is used;
## see expire.8
# How long to remember old history entries for.
