+# Logs are special: they are continously written to, may be compressed
+# have their file name changed in different, mutually incompatibly ways
+# and apprear and vanish at will. Handling this is a a complex and error-
+# prone issue.
+#
+# This is best broken down in a number of small tasks:
+#
+#
+# (A)
+# While a live log is being written to, it doesn't change its mode and
+# inode and its size only increases.
+#
+# (B)
+# When a live log is rotated for the first time, it should not change
+# its mode, may change its inode, and its size decreases. The size
+# decrease may not be noticed by aide if the file had size x at the last
+# aide run, was rotated in the mean time and was written to so that it
+# had a size > x at the next aide run.
+#
+# (C)
+# When a log is compressed, this looks to aide like the uncompressed
+# file vanished (or was replaced by another file) and the compressed
+# file appeared out of the blue. There is (currently) no way to
+# associate the (gone) uncompressed file's contents with the (new)
+# compressed file's contents
+#
+# (D)
+# The actual log rotation may rename foo.{x}.bar to foo.{x+1}.bar without
+# changing the other properties of the file
+#
+# (E)
+# If only a given number of log generations is to be kept, foo.{y}.bar may
+# vanish, but usually only when no foo.{z}.bar exists for z>y.
+#
+# (F)
+# The set of files foo.{x}.bar to foo.{y}.bar is called a "log series"
+# in aide terms, with the lowest x being called the "LoSerMember" element
+# and the highest y being called the "HiSerMember" element, and the z
+# with x<z<y simple called "SerMember". The Lo and Hi members need to
+# be special cased in aide configuration.
+#
+#
+# This is an example of the normal life of a log named foo in a logrotate
+# configuration using a configuration at it is commonly used in Debian
+# (from old to new):
+#     1 logrotate deletes HiSerMember foo.{y}.gz
+#     2 logrotate rotates SerMember foo.{z-1}.gz to foo.{z}.gz for all
+#       z with 3<z<=y. This includes rotation of foo.{y-1}.gz to
+#       foo.{y}.gz and foo.2.gz to foo.3.gz
+#     3 logrotate compresses foo.1 to foo.2.gz, creating LoSerMember foo.2.gz
+#     4 logrotate rotates foo to foo.1 (a simple rename)
+#     5 logrotate creates new, empty foo
+#     6 foo daemon logs to foo - foo grows in size
+#
+# we need the following rules:
+# /var/log/foo$ f Log
+# /var/log/foo$ f FreqRotLog
+#    this takes care of the growing live log (step 7). The "Log" rule
+#    is appropriate for logs that are not rotated daily as rotation
+#    might be reported (if the file size has decreased since the last
+#    aide run). For daily rotated logs, the "FreqRotLog" may be more
+#    appropriate.
+# /var/log/foo\.1$ f LowLog
+#    this takes care of step 5.
+# /var/log/foo\.2\.gz$ f LoSerMemberLog
+#    this allows yet unknown new files to appear with a \.2\.gz extension,
+#    covering step 3.
+# /var/log/foo\.[3..y-1]\.gz$ f SerMemberLog
+#    this watches the log files as they wander through the Series,
+#    changing only their file name but not their contents or metadata,
+#    covering step 2.
+#    Please note that [3..y-1] needs to be a manually crafted regexp covering
+#    all numbers between 3 and y-1.
+# /var/log/foo\.y\.gz$ f HiSerMemberLog
+#    finally, the last element of the Series is allowed to vanish without
+#    being reported, covering step 1.
+#
+# Please note that these example rules need to be adapted to the logrotate
+# configuration for the log. Compression may be disabled or lead to a different
+# extension, the dateext option may be used, old logs might be held in a
+# different place, a log series does not necessarily need to be compressed etc.
+#
+# Please note that savelog rotates the live log to .0 and not to .1 as it
+# is logrotates (changeable) default.
+
+
+# Logs grow in size. Log rotation of these logs will be reported, so
+# this should only be used for logs that are not rotated daily.
