+========================================================================
+Spec Lite: Add ability to purge all needed rows by glance-manage script.
+========================================================================
+
+:project: glance
+
+:problem: When a user wants to purge all deleted rows they use
+          "glance-manage db purge" and "glance-manage purge_images_table".
+          A user never knows how many deleted rows are still in a table.
+          So they need to launch the script many times until the script reports
+          that 0 rows were deleted in every table. It's inconvenient.
+
+:solution: use the same notation as with our other limits on "--max-rows" when
+           set to -1 it would purge them all rather than the default 100 lines
+           or what ever specified on the command line.
+
+:impacts: None
+
+:how: if "--max-rows" equals -1 the script purges deleted rows without number
+      limit.
+
+:alternatives: None
