10238	syslog pri part error in custom severity (init_from_stream)	anonymous	Andrey Semashev	"Hi all,
I'm trying to tune logging from settings to be able to send message to Syslog, TextFile and Console.
I use %Severity% keyword in all these cases. My task is get text value of severity in TextFile and Console,
and to get correct format of message in Syslog.

During executing the code below I've got an error pri part in SyslogViewer
[
#TextFile - OK
<DEBUG>[2014-Jul-24 10:27:28.611879]  This is a debug severity record
<INFO>[2014-Jul-24 10:27:28.627501]  This is a info severity record
<WARNING>[2014-Jul-24 10:27:28.658746]  This is a warning severity record
<ERROR>[2014-Jul-24 10:27:28.674369]  This is a error severity record
<CRITICAL>[2014-Jul-24 10:27:28.705613]  This is a critical severity record

#Syslog - ERROR PRI PART
<14> Jul  24 10:27:28 10.10.10.73 test.exe This is a debug severity record
<14> Jul  24 10:27:28 10.10.10.73 test.exe This is a info severity record
<14> Jul  24 10:27:28 10.10.10.73 test.exe This is a warning severity record
<14> Jul  24 10:27:28 10.10.10.73 test.exe This is a error severity record
<14> Jul  24 10:27:28 10.10.10.73 test.exe This is a critical severity record
]
Every record has Syslog pri part equals to <14>. That is mistake!

P.S. If I use int instead of enum as severity level, everything is ok in Syslog,
but in this case I can not get text values of %Severity% in TextFile and Console
[
#TextFile - I need %Severity% as text here

P.S.2. In my opinion problem is in $(BOOST_ROOT_55)\libs\log\src\init_from_settings.cpp, line 453:
{{{
	// For now we use only the default level mapping. Will add support for configuration later.
	backend->set_severity_mapper(sinks::syslog::direct_severity_mapping< >(log::aux::default_attribute_names::severity()));
