It would be nice if the build system would automatically issue a log file or at least log message about build time and usage statistics. If it wouldn't tell about my brain's age, I would politely ask to have a "flower box"... ;-) -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
