Anthony,

	I'm quite new to buildbot. I've been experimenting with some code to upload a binary 
distribution after a build:

class DistFileUpload(FileUpload):
     def __init__(self, slavesrc, masterdest,
                  workdir=None, maxsize=None, blocksize=16*1024, mode=None,
                  **kwargs):
         FileUpload.__init__(self, slavesrc, masterdest,
                             workdir, maxsize, blocksize, mode,
                             **kwargs)

     def finished(self, result):
  #       if result == SUCCESS:
         buildnumber = self.getProperty("buildnumber")
         buildername = self.getProperty("buildername")
         url = "http://<hostname>/hello-%s-%s.tar" % (buildnumber, buildername)
         self.addURL("Binary",url)
         return FileUpload.finished(self,result)

f1 = factory.BuildFactory()
f1.addStep(CVS(cvsroot=cvsroot, cvsmodule=cvsmodule, login=None, mode="copy"))
f1.addStep(Compile(
            command=["make"]))
# Pass the buildnumber and builder name to the make file so that it can
# use them as part of the file anme
f1.addStep(Compile(
            command=["make", "dist",
                     WithProperties("buildno=%s", "buildnumber"),
	            WithProperties("builder=%s", "buildername")],
            description = ["building dist"],
            descriptionDone = ["distribution"]))

# Upload the file to the master and add url link to it.
f1.addStep(DistFileUpload(
            mode = 0644,
            slavesrc=WithProperties("hello-%s-%s.tar", "buildnumber", "buildername"),
            masterdest=WithProperties("~/builds/hello-%s-%s.tar", "buildnumber", 
"buildername")))

The class DistFileUpload takes care of uploading the file and then adding the link to the 
waterfall display.

There may be better, cleaner ways to do this, but this is working except for the test for 
SUCCESS in DistFileUpload.finished.
