Uses the VCS to compare the current tree with a previous tree, and
prints a pretty report. If REVISION is given, it is a specifier for
the particular previous tree to use. Specifiers are specific to their
VCS.
For Arch your specifier must be a fully-qualified revision name.
Besides the standard summary output, you can use the options to output
UUIDS for the different categories. This output can be used as the
input to 'be show' to get an understanding of the current status.
