       This package adds template based appenders.

       ::logger::utils::createFormatCmd formatString
              This  command  translates  formatString  into  an  expandable  command string.  The
              following strings are the known substitutions (from log4perl) allowed to  occur  in
              the formatString:

              %c     Category of the logging event

              %C     Fully qualified name of logging event

              %d     Current date in yyyy/MM/dd hh:mm:ss

              %H     Hostname

              %m     Message to be logged

              %M     Method where logging event was issued

              %p     Priority of logging event

              %P     Pid of current process

       ::logger::utils::createLogProc -procName procName ?options...?
              This command ...

              -procName procName
                     The name of the procedure to create.

              -conversionPattern pattern
                     See  ::logger::utils::createFormatCmd  for  the substitutions allowed in the

              -category category
                     The category (service).

              -priority priority
                     The priority (level).

              -outputChannel channel
                     channel to output on (default stdout)

       ::logger::utils::applyAppender -appender appenderType ?options...?
              This command will create an appender for  the  specified  logger  services.  If  no
              service  is  specified  then the appender will be added as the default appender for
              the specified levels. If no levels are specified, then all levels are assumed.

              -service loggerservices

              -serviceCmd loggerserviceCmds
                     Name of the logger instance to modify. -serviceCmd takes as input the return
                     of logger::init.

              -appender appenderType
                     Type of the appender to use.  One of console, colorConsole.

              -conversionPattern pattern
                     See  ::logger::utils::createFormatCmd for the format of the pattern. If this
                     option is not provided the default pattern

                     [%d] [%c] [%M] [%p] %m

                     is used.

              -levels levelList
                     The list of levels to apply this appender to. If not  specified  all  levels
                     are assumed.

       Example of usage:

                 % set log [logger::init testLog]
                 % logger::utils::applyAppender -appender console -serviceCmd $log
                 % ${log}::error "this is an error"
                 [2005/08/22 10:14:13] [testLog] [global] [error] this is an error

       ::logger::utils::autoApplyAppender command command-string log op args...
              This  command  is designed to be added via trace leave to calls of logger::init. It
              will look at preconfigured state (via ::logger::utils::applyAppender) to autocreate
              appenders for newly created logger instances.  It will return its argument log.

              Example of usage:

                logger::utils::applyAppender -appender console
                set log [logger::init applyAppender-3]
                ${log}::error "this is an error"
