Is it possible to configure AccuRev to use WinMerge as its diff/merge tool?

I see in AccuRev's Diff/Merge Preferences tab that the diff and merge tools can be switched to a pre-defined list of third-party tools.

These are the choices I have:

Diff

• AccuRev
• TkDiff
• Araxis
• BeyondCompare V1
• BeyondCompare V2
• Guiffy

Merge

• AccuRev
• TkDiff
• Araxis
• Guiffy

Is it possible to add WinMerge to these lists? If so, how?

you can not only chose from the list but also insert any cmdline you need to run, so you can hook in any diff/merge tool that supports being called with parameters. e.g. I use this for diffing:

NxNMerge.exe %1% %2% /title1:"%3%" /title2:"%4%"

For a description of the parameters open the Tools->Preferences->Diff/Merge in AccuRev and click on the help button.
