a few posts ago i showed how to convert the SuSE *.rpm’s from the google-gadgets-for-linux project, into slackware packages.
well for a couple of their releases now, i’ve been maintaining a Slackware build script. you can browse it on my viewcvs or check it out on subversion

svn co svn://hashbangbash.com/src/pub/SlackBuilds/google-gadgets/

have fun !
