spamfolder?

[Dave Abrahams]

The example conf file includes this unexplained segment:

# The trash folder name may be different from [Gmail]/Trash
# for example on german googlemail, this setting should be
#
# trashfolder = [Google Mail]/Papierkorb
#
# The same is valid for the spam folder
#
# spamfolder = [Google Mail]/Spam

I understand the significance of trashfolder of course, but what is
offlineimap's interest in spamfolder?
