</dt> <dd> 
The resulting archive will be compressed as specified. 
Note that the compressed output is always properly blocked. 
</dd><dt> 
'''archive_write_add_filter_b64encode'''(), 
'''archive_write_add_filter_uuencode'''(), 
</dt> <dd> 
The output will be encoded as specified. 
The encoded output is always properly blocked. 
</dd><dt>'''archive_write_add_filter_none'''()</dt><dd> 
This is never necessary. 
It is provided only for backwards compatibility. 
</dd><dt>'''archive_write_add_filter_program'''()</dt><dd> 
The archive will be fed into the specified compression program. 
The output of that program is blocked and written to the client 
write callbacks.
