There are many ways to read comic books, and one of those that has become more common in recent years is on a computer. Peruse was created as a way to make exactly that as easy and pleasant as possible, and to simply get out of the way and let you read your comic books. One could say that it allows you to peruse your comic books at your leisure, but that would be a silly way of putting it - so, peruse your comic books at your leisure! (from the Peruse website)
Peruse provides also a comic creator. You can edit metadata and add new pages.
