Re: Two people adding the same file - can both versions be merged?

1. Does the tool provide the feedback to the second developer to
resolve the problem.
2. Is the resolution straightforward enough to apply without a visit
to documentation or using tools not common to the usual workflow.

Subversion seems to provide for the first point well enough. The
attempted commit produces

  "svn: File already exists: filesystem 'C:/_repositories/svn/db',
transaction '8-1', path 'thefile.txt"

and updating produces

  "svn: Failed to add file 'thefile.txt': object of the same name
already exists"

I'm not sure that the second part is addressed as well. Dev B can
certainly revert his file, rename it and do an update for get the
content from Dev A. Now however Dev B has to manually merge his
content into Dev A's file before committing his content. It might be
better, in the conflict update case to output the appropriate message
but also provide the conflict files

   "thefile.txt.mine"
   "thefile.txt.r0" (an empty file)
   "thefile.txt.rN" (where N is the newly updated revision from Dev A)

Now Dev B can use their usual work-flow for conflict resolution to
merge the content. This task is likely to be much more familiar to
the developer.
