 Limitations
 ===========
 
-1. Metadata is currently ignored. I haven't noticed any metadata blocks in any
-   SWF files I've disassembled.
-
-2. Private namespaces are currently represented by an automatically-assigned 
-   integer. This causes problems when comparing disassemblies from two 
-   versions of a file, since those numbers are prone to change when classes
-   are added or removed.
-
-3. `rabcasm` may create a broken file due to not ordering classes by ancestry.
-
-   The problem originates from the fact that a class's ancestors (extended 
-   class and implemented interfaces) are stored as multinames, and not as 
-   class indices. (This makes sense, since classes may extend objects outside 
-   the current ABC file.) Since `rabcasm` currently doesn't decode multinames, 
-   it is unaware of the class dependencies, and may thus write the classes out 
-   of order. This results in a file that, when opened, will fail to load with 
-   an error message similar to:
-
-        VerifyError: Error #1014: Class AncestorClassName could not be found.
-
-   The simple work-around is to re-order the classes as they are declared in 
-   the `.main.asasm` file, and place ancestors before descendants.
