ComicMaster is a CBR/CBZ reader for comic archives. It is able to open CBR and CBZ archives and display image contents. It allows you to add and remove single images, reorder images, and rename images in archives. It has some functionality to verify archives, and provides means to conveniently sort archives in a different folder. Those features are fairly well tested. It allows you to load a database plugin to manage comics in a PostgreSQL database, and it allows you to add meta-information in XML format to archives. The implementation of these features is currently sketchy at best.
