Oh, it's caused by the include grammar. I need to check how to solve the
relative path problem with include grammar in shell script. It should not
be difficult.

No problem, I will unify all error messages.

It's expected behavior. Since powerpcc is the correct name.

Log file problem is solved totally by replacing " >> " with "&>>" pointed by Lianhao.

Missing guard will be added here. 
I will send the updated scripts which will address most of the problem.


Btw: I need someone review the script totally. I am afraid some of the scripts
Might not obey shell's world conventions since this is the first script I wrote.
I have to say I did try several blackbox test yet failed to cover all corner problems.

Updated scripts will soon be published.
