[Gambas-user] how to log to stdout/stderr

[PICCORO McKAY Lenz]

in part you have right fernando.. but that was dicuss several time
previously.. i want to no made special commands to daemonize my app.. i
want my app are daemon by selft..

now my app are a property daemon.. and every night at 00:00 restart all
setting and starts a new day to regist people..

the log must also be manage by the application.. if not then its not a
proper daemon..

the nohup trick not always work.. for that there's the gambas redirection
print.. that's why i ask previously how i detec if are runnig inside ide..
if are inside ide. let normal print, if not, redirect...
