## Template Type:
## -------------
## 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 RebasedPatchSet.vm template will determine the contents of the email
## related to a user rebasing a patchset for a change through the Gerrit UI.
## It is a ChangeEmail: see ChangeSubject.vm and ChangeFooter.vm.
