I typed more than thought yesterday
3d does use "..." but not for versioning
we only versioned regular files
a versioned filed accessed as
"foo"
to see all the versions acces the file as a directory
"foo/"
pysically the latest version was a hard link to a file like
"foo/1.2.3.4"
had we versioned directories we would have had to encroach the namespace
