Quoting from above message:
 1. <prefix>/share/roundup/templates/*
 2. <roundup.admin.__file__>/../templates/*
 3. <current working dir>/*
 4. <current working dir>

The doc string of roundup.AdminTool.listTemplates() states
"Look in three places" which should be "four places".

And all this is undocumented, except for this bug and the
corresponding message on roundup-devel.
