# Generate a nice changelist by querying perforce.

|
#
|

# Each change is described with the change number, description,
|
||
|
|
# which branch the change happened in, files modified,
|
||
|
|
# and who was responsible for entering the change.
|
||
|
|
#
|
||
|
|
# Can be called with a list of change numbers or a range of the
|
||
|
|
# form "12..42". Changelog will be printed from highest number
|
||
|
|
# to lowest.
|
||
|
|
#
|
||
|
|
# Outputs the changelist to stdout.
