       Using this hook, it is easy to generate mails describing the updates to the repository. This example script sends one mail message per ref listing the
       commits pushed to the repository:


           #!/bin/sh
           # mail out commit update information.
           while read oval nval ref
           do
                   if expr "$oval" : '0*$' >/dev/null
                   then
                           echo "Created a new ref, with the following commits:"
                           git-rev-list --pretty "$nval"
                   else
                           echo "New commits:"
                           git-rev-list --pretty "$nval" "^$oval"
                   fi |
                   mail -s "Changes to ref $ref" commit-list@mydomain
           done
           exit 0
