7-Zip Tasks for NAnt

Hi!

Out of personal need (limited bandwidth for my continuous integration 
server) I wrote myself some NAnt tasks for creating 7-Zip archives. I 
intentionally didn't include any of the 7-Zip code but call 7z.exe 
(Windows) or 7za (Linux) which is located using the Registry (Windows 
only) or default paths (Windows and Linux).

Here's a usage example:

<sevenzip-compress archive="archive.7z" level="9" password="secret">
<fileset basedir="..">
<include name="Source/**/*" />
<exclude name="**/*.txt" />
</fileset>
</sevenzip-compress>

<sevenzip-extract archive="archiv.7z" todir="test" password="secret" />

Is there any interest for such a thing for NAnt/NAntContrib?

- I chose to create different tasks for compression and extraction 
because the parameters are different (and I didn't like how NAnt-Contrib 
designed the <svn /> task).
- Relying on an external executable has the advantage of not requiring 
different builds of the DLL for different platforms, but has the 
disadvantage of requiring 7-Zip to be installed on the build system. If 
am thinking about adding a 'path' parameter to the tasks so it's 
possible to specify which 7z.exe/7za to use, but this would also entail 
shipping 7-Zip binaries for all supported platforms with a development 
tree. The fate of the <nunit2 /> task ultimately convinced me that using 
the 7-Zip executable is better.

If anyone wants to check it out:
Source code (VS2010): 
https://devel.nuclex.org/sideprojects/svn/tasks/Nuclex.NAnt.Tasks/trunk/
Binaries: 
https://devel.nuclex.org/teamcity/viewLog.html?buildId=lastSuccessful&tab=artifacts&buildTypeId=bt3&guest=1 
<https://devel.nuclex.org/teamcity/viewLog.html?buildId=lastSuccessful&tab=artifacts&buildTypeId=bt3&guest=1>

The binaries are built against NAnt.Core from NAnt 0.90.3780.0. I 
haven't tried what happens when I attempt to load them with another NAnt 
release.
