Support for comic book aliases

 If you wish to exclude non-free code from your build, you can disable RAR support
 by building without the `unrar` feature.
 
-`tar` aliases are also supported: `tgz`, `tbz`, `tbz2`, `tlz4`, `txz`, `tlzma`, `tsz`, `tzst`.
+Aliases for these formats are also supported:
+- `tar`: `tgz`, `tbz`, `tbz2`, `tlz4`, `txz`, `tlzma`, `tsz`, `tzst`, `cbt`  
+- `zip`: `cbz`
