Subject Re: [general] creation of "jdktools"
Date Tue, 31 Oct 2006 11:49:06 GMT
Take me for example. I will be most likely misleaded with "build"
since the majority of projects I've seen in my life were using "build"
or "build.<platform>" for  storing build artifacts (as Mark said). I
agree it is logically to call it "build". But "make" is logical too.
"ant" or "ant.scripts"  also sound not so bad. Why not to choose the
less confusing name?

With best regards,
