bmaptool is a generic tool for creating the block map (bmap) for a
file, and copying files using the block map. The idea is that large
file containing unused blocks, like raw system image files, can be
copied or flashed a lot faster with bmaptool than with traditional
tools like "dd" or "cp".

bmap-tools (3.2-2) unstable; urgency=medium
* Add patch to make the child process for transparent uncompression
read the compressed file directly if possible, avoiding blocking
forever in join() if the read thread does not terminate

* New upstream release
* Correct debian/changelog syntax in entries from upstream
