[Zope] - Where is misc_/sample/item?

[skip@calendar.com (Skip Montanaro)]

In the sample product, Product.py defines

    # Specify a relative URL for the icon used to display icons:
    icon='misc_/sample/item'

In the MailHost product, MailHost.py defines

    icon='misc_/MailHost/MHIcon'

Where are these things located?  I couldn't find a directory named "misc_"
anywhere, nor could I figure out how to get at any such beasts from within
the management interface.

thx,
