3# Generate a nice changelist by querying perforce.
4#
5# Each change is described with the change number, description,
6# which branch the change happened in, files modified,
7# and who was responsible for entering the change.
8#
9# Can be called with a list of change numbers or a range of the
10# form "12..42". Changelog will be printed from highest number
11# to lowest.
12#
13# Outputs the changelist to stdout.
