Could you add an option to strip the prefix from the enumeration keys. For example given following C code:

enum abc_some_enum {
  abc_some_enum_key1,
  abc_some_enum_key2,
  abc_some_enum_key3,
};

The expected C# output is following:

enum abc_some_enum {
  key1,
  key2,
  key3,
};

My best guess is that generator should cut maximum common prefix from the enum key name.
