+## This is a velocity mail template, see: http://velocity.apache.org and the
+## gerrit-docs:config-mail.txt for more info on modifying gerrit mail templates.
+##
+## Template File Names and extensions:
+## ----------------------------------
+## Gerrit will use templates ending in ".vm" but will ignore templates ending
+## in ".vm.example".  If a .vm template does not exist, the default internal
+## gerrit template which is the same as the .vm.example will be used.  If you
+## want to override the default template, copy the .vm.example file to a .vm
+## file and edit it appropriately.
+##
+## This Template:
+## --------------
+## The DeleteReviewer.vm template will determine the contents of the email
+## related to removal of a reviewer (and the reviewer's votes) from reviews.
+## It is a ChangeEmail: see ChangeSubject.vm and ChangeFooter.vm.
+##
+$fromName has removed $email.joinStrings($email.reviewerNames, ', ') from this change.
