Prints a brief help message to the standard output and exits.
.IP "\fB\-\-perl\fR=VERSION" 4
.IX Item "--perl=VERSION"
This displays dependencies which have been available in Perl core since
the given \s-1VERSION.\s0 It does not currently know if a module has been removed
from core, but this is an unlikely occurrence. Specify Perl versions in
the form:
.Sp
.Vb 2

.IP "\fB\-\-phase\fR=PHASE" 4
.IX Item "--phase=PHASE"
This displays dependencies which are needed for a given module's install
or runtime \s-1PHASE.\s0 Available phases are:
.RS 4
.IP "\(bu" 4
runtime: required whenever the module is used
.IP "\(bu" 4
build: required to build the module
.IP "\(bu" 4
configure: these are required while preparing the module for
build

.IP "\fB\-\-rankdir\fR" 4
.IX Item "--rankdir"
In GraphViz, the 'rankdir' attribute controls the direction that the nodes
are linked together. If set, the graph will use left \-> right linking of
nodes rather than the default up-down linking.
.IP "\fB\-\-reverse\fR" 4
.IX Item "--reverse"
Create a graph of the reverse dependencies of a package (the packages which
depend on it, or dependent packages).
.IP "\fB\-\-verbose\fR" 4
.IX Item "--verbose"
Display extra output useful during debugging.
.SH "DESCRIPTION"

\&\fBThis script\fR will use the \s-1CPAN\s0 Database to build a graph of a package's
