[Mono-list] RemoveDir - XBuild vs MSBuild

[Mike Christensen]

I'm trying to port an MSBuild script to XBuild and running into the
following issue:

<RemoveDir Directories="Imp/bin" />

This crashes and stops building if Imp/bin does not exist.  On
MSBuild, it will just do nothing and ignore the command.

Is this a bug?  Is there any way I can say "delete the directory if it exists?"

Thanks!

Mike
