+    The branchmap is a file that allows you to rename a branch when it is
+    being brought in from whatever external repository. When used in
+    conjunction with a splicemap, it allows for a powerful combination
+    to help fix even the most badly mismanaged repositories and turn them
+    into nicely structured Mercurial repositories. The branchmap contains
+    lines of the form "original_branch_name new_branch_name".
+    "original_branch_name" is the name of the branch in the source
+    repository, and "new_branch_name" is the name of the branch is the
+    destination repository. This can be used to (for instance) move code
+    in one repository from "default" to a named branch.
