The core client writes error messages to stderr.
|
|
|
|
|
This mechanism is reserved for serious problems,
|
|
|
|
|
i.e. those that reflect bugs in the core
|
2002-07-29 19:01:38 +00:00
|
|
|
client program or conditions that require user intervention.

|
In addition, the core client can write a variety of "logging"
|
|
|
|
|
information to stdout.
|
|
|
|
|
The logging options are read from a file
|
|
|
|
|
<b>log_flags.xml</b>.
|
|
|
|
|
This file has the following format:
|
