NAME
       L - generate logging messages in C and C++.

SYNOPSIS
       #include <L.h>

       L(format,...)

       LG(guard,format,...)

       LH(handler,format,...)

DESCRIPTION
       The L macro is used to print logging or debugging messages.

       format,... - a printf(3) style argument list containing the message

       guard - print only if the guard is true.

       handler - the code that does the printing, e.g. support is provided for
       sending log messages to a circular buffer.

       param - a parameter to be passed off to the handler, e.g. a file
       descriptor.

       See nana.info for details on configuring the behaviour.  You also need
       to include the nana library by using -lnana if you use the default
       setup.
