Stefan Bodewig commented on COMPRESS-352:
-----------------------------------------

could you please give commit 18daf66 a try? I decompresses a single IWA I've 
taken from Tika's numbers example, but I lack knowledge of the expected output 
so have to defer to you to see whether decompression is correct.

> Add snappy decompressor that handles Apple .iwa files

> On TIKA-1966, one of our users recently shared the newest iOS iWorks files.  
> They've gotten rid of internal .zip and now rely exclusively on .iwa files.  
> commons-compress doesn't currently appear to handle these 
> (snappy-compressed?) files...probably because:
> bq. However, the variant of Snappy that is used does not comply with the spec 
> for that format, omitting the stream identifier and checksum.
> from  http://fileformats.archiveteam.org/wiki/IWA
> Any chance you'd be able to modify the snappy decompression to handle Apple's 
> variant?
