+.SH GITATTRIBUTES
+git has features which can automatically transform files
+as they are being copied between the working tree
+and the git history.
+See \fBgitattributes\fP(5).
+
+These transformations are context-sensitive
+and not, in general, reversible,
+so dgit operates on the principle that
+the dgit git history contains the actual contents of the package.
+(When dgit is manipulating a .dsc,
+it does so in a private area,
+where the transforming gitattributes are defused (disabled),
+to achieve this.)
+
+If transforming gitattributes used,
+they can cause trouble,
+because the working tree files can differ from
+the git revision history
+(and therefore from the source packages).
