Adjusting Linebreak Policy</h1>

By default, output destinations (but not <code>log4cplus</code> or
<code>fwkJobReport</code> destinations) are formatted by injecting line
breaks between items if a line would exceed 80 characters. This
formatting can be controlled and/or disabled:
<pre>
process TEST = {
service = MessageLogger {
vstring destinations = { "detailedInfo.txt"
, "critical.txt"
}
PSet critical.txt = { <font color=red>bool noLineBreaks = true</font> }
PSet detailedInfo.txt = { <font color=red>int32 lineLength = 132</font> }
}
untracked PSet maxEvents = {untracked int32 input = 5}
path p = { myAnalysisModule }
module myAnalysisModule = ModuleThatIssuesMessages { }
source = EmptySource { }
}
</pre>
The <font color=red>bool noLineBreaks = true</font> parameter
in the PSet configuring <font color=red>critical.txt</font> tells the
destination producing the file critical.txt not to add line breaks
which would format the message for an 80-column screen.
Files which will be parsed by automated utilities might be easier to handle
without logger-produced line breaks within a message.
<p>
The <font color=red>int32 lineLength = 132</font> parameter
in the PSet configuring <font color=red>detailedInfo.txt</font> tells the
destination producing the file detailedInfo.txt not format the message for a
132-column window.
