docs/README.suite-removal

+[ This was some notes to myself that I made while removing potato; I
+  kept it because it turned out to be a far more traumatic experience
+  than was necesary.  Hopefully rhona will be fixed by the time I need
+  to do this again which would obsolete most of the complex SQL
+  crap. (JT) ]

+
+			 Potato Removal Plan
+			 -------------------
+
+o Create potato copy on archive.debian.org
+o poolize any not-just-potato files with monica.
+o force-remove any just-potato files (i.e. by setting last used to 3 weeks ago and run rhona)
+o remove any files (dists/potato) (NB: not pool symlinks!)
+o remove oldstable etc. from the db and config files
