+If most of your commits lack proper author names (as will be the case
+if your repository was generated by linkgit:git-svn[1]), you can
+generate most of a correct `.mailmap` automatically like this:
+
+------------
+git log "--pretty=%an <%ae>" | sort | uniq > .mailmap
+------------
+
+You will then have to edit the file to add the proper author names.
