28# Display SVN log entries for changesets which have files which were
29# Added or Deleted.
30# This script takes arguments which would normally be
31# passed to the "svn log" command.
32#
33# Examples:
34#
35#  (1) Display all new changesets in stable/10 branch:
36#
37#        list-new-changesets.py --stop-on-copy \
38#                        svn://svn.freebsd.org/base/stable/10
39#
40#  (2) Display all new changesets between r254153 and r261794 in
41#      stable/9 branch:
42#
43#        list-new-changesets.py  -r254153:261794 \
44#                        svn://svn.freebsd.org/base/stable/9
