| /* class VBA: |
| * The VBA class provides a set of methods to handle Visual Basic For |
| * Applications streams, the constructor is given the root ole2 stream |
| * of the document, Open reads the VBA project file and figures out |
| * the number of VBA streams, and the offset of the data within them. |
| * Decompress decompresses a particular numbered stream, NoStreams returns |
| * this number, and StreamName can give you the streams name. Decompress |
| * will return a string with the decompressed data. The optional extra |
| * argument will be set if not NULL to 1 in the case of a string overflow, |
| * if I can figure out how to do that. |
| * |
| * Otherwise it is possible to inherit from VBA and implement a Output |
| * member which gets called with each 4096 output sized block. |
