!! \s-1THIS COMMAND IS EXPERIMENTAL\s0 !!
.PP
This command shows the difference between two stacks or revisions, presented
in a format similar to diff[1].
.SH "COMMAND ARGUMENTS"
.IX Header "COMMAND ARGUMENTS"
Command arguments are the names of the stacks or revision IDs to compare. If
you specify a stack name, the head revision of that stack will be used.  If
you only specify one argument, then it is assumed to be the \s-1RIGHT\s0 and the head
revision of the default stack will be used as the \s-1LEFT.\s0  Revision IDs can be
truncated to uniqueness.
.SH "COMMAND OPTIONS"
.IX Header "COMMAND OPTIONS"
.IP "\-\-diff\-style=STYLE" 4
.IX Item "--diff-style=STYLE"
Controls the style of the diff reports.  \s-1STYLE\s0 must be either \f(CW\*(C`concise\*(C'\fR or
\&\f(CW\*(C`detailed\*(C'\fR.  Concise reports show only one record for each distribution added
or deleted.  Detailed reports show one record for every package added or
deleted.
.Sp
The default style is \f(CW\*(C`concise\*(C'\fR.  However, the default style can be changed by
setting the \f(CW\*(C`PINTO_DIFF_STYLE\*(C'\fR environment variable to your preferred \s-1STYLE.\s0
This variable affects the default style for diff reports generated by all
other commands too.
.IP "\-\-format=FORMAT" 4
.IX Item "--format=FORMAT"
A \f(CW\*(C`printf\*(C'\fR\-style format string describing how individual lines of the diff are
to be printed.  For the description of the \f(CW\*(C`FORMAT\*(C'\fR, please refer to
\&\*(L"\s-1COMMAND OPTIONS\*(R"\s0 in App::Pinto::Command::list.
.Sp
The default format for \f(CW\*(C`concise\*(C'\fR diffs is \f(CW\*(C`%o[%F] %a/%f\*(C'\fR.  The default format
for \f(CW\*(C`detailed\*(C'\fR diffs is \f(CW\*(C`%o[%F] %\-40p %12v %a/%f\*(C'\fR.
