+IntelliJ Platform log all STDOUT and STDERR output to idea.log file by default.
+See com.intellij.idea.StartupUtil#setupLogger system property 'intellij.log.stdout'.
+
+Two main appenders are FILE and DIALOG:
+FILE is responsible for logging to the idea.log file.
+DIALOG is responsible for showing ERROR level (at least) events in UI (events are ignored in command line mode).
+
+MPS additionally logs VCS events to mpsvcs.log file: categories are used for that.
+
+Appenders CONSOLE-* can be used to debug purposes to get application output to the console.
+
+CONTINUOUS_FILE appender can also be used for debugging.
+It does not interfere with console output and idea.log, but uses separate continuous.log file.
+
+All file appenders use $LOG_DIR$ folder for store files.
+In MPS sources some run configurations override this path by setting 'idea.log.path' variable to '$PROJECT_DIR$/log'.
