%description
This module provides a simple object for logging to files under the
Log::Dispatch::* system, and automatically rotating them according to
different constraints. This is basically a Log::Dispatch::File wrapper with
additions. To that end the arguments

name, min_level, filename and  mode

behave the same as Log::Dispatch::File. So see its man page (perldoc
Log::Dispatch::File)

The arguments size and max specify the maximum size and maximum number of
log files created. The size defaults to 10M and the max number of files
defaults to 1. If DatePattern is not defined then we default to working in
size mode. That is, use size values for deciding when to rotate.

Once DatePattern is defined FileRotate will move into time mode. Once this
happens file rotation ignores size constraints, unless check_both, and uses
the defined date pattern constraints.

If you setup a config file using Log::Log4perl::init_and_watch() or the
like, you can switch between modes just by commenting out the DatePattern
line.

When using DatePattern make sure TZ is defined correctly and that the TZ
you use is understood by Date::Manip. We use Date::Manip to generate our
recurrences. Bad TZ equals bad recurrences equals surprises! Read the
Date::Manip man page for more details on TZ.

DatePattern will default to a daily rotate if your entered pattern is
incorrect. You will also get a warning message.

If you have multiple writers that were started at different times you will
find each writer will try to rotate the log file at a recurrence calculated
from its start time. To sync all the writers just use a config file and
update it after starting your last writer. This will cause
Log::Dispatch::FileRotate->new() to be called by each of the writers close
to the same time, and if your recurrences aren't too close together all
should sync up just nicely.

I initially assumed a long running process but it seems people are using
this module as part of short running CGI programs. So, now we look at the
last modified time stamp of the log file and compare it to a previous
occurance of a DatePattern, on startup only. If the file stat shows the
mtime to be earlier than the previous recurrance then I rotate the log
file.

We handle multiple writers using flock().
