title: Set up TortoiseMerge as external merge tool for SVN?
body: <p>Is it possible to set up TortoiseMerge (comes with TortoiseSVN) to be the external merge tool that pops up when you encounter a merge conflict using the "svn merge" commandline? I have tried setting my environment variable "SVN_MERGE" to point to TortoiseMerge.exe, but this doesn't seem to be enough. TortoiseMerge just pops up when I choose "l" (to launch an external tool) asking me what files I want to merge. I want this information to be pushed into the tool automatically.</p>
  
  <p>Any ideas?</p>
