[nem-en] Assembly Version from SVN

[vc]

Hi,

Unfortunately the Nemerle.MSBuild.Tasks.nproj where you use this attribute
does not build. Error message:
nemerle\tools\msbuild-task\MSBuildTask.n(42,12,42,48): error : 
the custom attribute `AssemblyVersionFromSVN ("0.9.3.SVN")' 
could not be found or is invalid

It's bad way.

In svn://rsdn.ru/Janus/trunk/SvnRevision you can find simple implementation
same logic on C#. It's implementation simply scan SVN's files and retrieve
version.

It's bad approach. For example, on my PC svn.exe do not installed. I use
TortoiseSVN which use dll's for communication with SVN.

I like it.

No. Not oll OK. :(
