Authoring with fade ins/outs

[DeafMute]

Hello.

I've just finished mastering a little project that contains 4 tracks that are meant to be heard as a one single piece.
I don't own any CD authoring tools for Mac, I know DP6 can do it, but I'm still running 5.
Does anyone know of any open source cd authoring tools for Mac? I´m obviously most concerned with the ability to number the tracks even if they are a continuous piece of audio.

Thanks.

I ended up taking a different approach on this. I bounced all the songs as one continuous file.
Then, imported them into a new session where I separated them and then burned the CD on iTunes as a "gapless cd".
It worked...
