Ancestry Lines

The Version Browser uses these color-coded lines to indicate ancestry relationships

•	direct ancestor (black) -- A user started with the earlier version, modified (or overwrote) it, and then performed a Keep, creating the later version. (There are a few other operations, including Rename, that might have created the later version. See below for details.)

•	alias (green) -- A user promoted the earlier version to create the later version.

•	merge (red) -- A user executed a Merge operation to create the later version. There are always two earlier versions: the black line indicates the direct ancestor (see above) of the later version; the red line indicates the version that was merged with the direct ancestor.

•	patch (dashed green) -- Similar to merge above, but the later version was created by Patch.

•	revert (dashed blue) -- The later version was created by a 'reverse patch', performed by Revert. This effectively 'undoes' the changes in a specified transaction or change package.

•	purge (blue) -- The version in the user’s workspace was restored to an earlier version with a Purge (Revert to Basis) operation.
