NAME

cpangraph - Generate dependency chain graphs for CPAN modules

VERSION

Version 0.12

SYNOPSIS

   cpangraph [options] <file>
 
     Options:
       --help            display a brief help message
       --perl=VERSION    filter those available in Perl core
       --phase=PHASE     filter those needed for a phase (e.g., build)
       --rankdir         controls the GraphViz 'rankdir' variable
       --reverse         graph reverse dependencies (dependents)
       --verbose         display additional debugging information
 
 

OPTIONS

--help

Prints a brief help message to the standard output and exits.

--perl=VERSION

This displays dependencies which have been available in Perl core since the given VERSION. 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:

   5.008008 # for versions >= 5.8.8
   5.010    # for versions >= 5.10
 
 

--phase=PHASE

This displays dependencies which are needed for a given module's install or runtime PHASE. Available phases are:

•

runtime: required whenever the module is used

•

build: required to build the module

•

configure: these are required while preparing the module for build

--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.

--reverse

Create a graph of the reverse dependencies of a package (the packages which depend on it, or dependent packages).

--verbose

Display extra output useful during debugging.

DESCRIPTION

This script will use the CPAN Database to build a graph of a package's dependencies or reverse dependencies (dependent packages).
