[Alug] Burning CDs

Having now managed to install my CD-RW drive and load up cdrecord 1.10 in Slackware, I've started to fiddle with actually making CDs. I downloaded Xcdroast and managed to get it to run, but I can't find any buttons at all that erase a previously recorded CD-RW disk and it seems that Xcdroast won't just simply write the new files to a previously recorded CD-RW disk. Am I missing something obvious? Is Xcdroast the best front-end for the CD-writing process? I picked it because I could get a .TGZ file already to install in Slackware. (Alright - call me chicken!) As always, all advice very gratefully received! Gerald.
