• src/pmdas/logger/loggerMain.c: Ditto.
• src/pmdas/logger/GNUmakefile.in: Removed logger.h and loggerMain.c references.
• src/pmdas/logger/event.c (event_init): Opens logfile.
• src/pmdas/logger/event.h: Updated event_init() prototype.
• src/pmdas/logger/logger.c (logger_init): Calls event_init(). (main): Calls pmdaMain() instead of old custom loggerMain().
