That's exactly what Module::Dependency will (now) do. Except that the
output is upside down since I'm using a parents and children analogy.
For example, to show one level of parent dependencies and two levels of
child dependencies for ExtUtils::MakeMaker, while only showing each
module once, you could say:
$ pmd_dump.pl -f=key -h -p=1 -c=2 -U ExtUtils::MakeMaker
Carp
Cwd
Data::Dumper
Exporter
ExtUtils::MM
ExtUtils::MY
ExtUtils::MakeMaker::Config
ExtUtils::Manifest
File::Path
File::Spec
VMS::Filespec
strict
vars
ExtUtils::MakeMaker
ExtUtils::Installed
/bin/cpan/instmodsh
ExtUtils::MM_AIX
ExtUtils::MM_Any
ExtUtils::MM_BeOS
ExtUtils::MM_Cygwin
ExtUtils::MM_DOS
ExtUtils::MM_OS2
ExtUtils::MM_Unix
ExtUtils::MM_VMS
ExtUtils::MM_Win32
ExtUtils::MM_NW5
ExtUtils::MM_OS2
ExtUtils::MM_Unix
ExtUtils::MM_QNX
ExtUtils::MM_UWIN
ExtUtils::MM_VOS
ExtUtils::MM_VMS
ExtUtils::MM_Win32
ExtUtils::MM_Win95
Module::Build::Compat
Module::Build::Base
Changing the -f=key to -f=filename and removing the -h would make each
like look like:
ExtUtils::MM_AIX filename: path/to/lib/site_perl/ExtUtils/MM_AIX.pm
