check_requirements($reqs,$type,$incdirs)
This function checks if all dependencies in $reqs (a CPAN::Meta::Requirements object) are met, taking
into account that 'conflicts' dependencies have to be checked in reverse. It returns a hash with the
modules as keys and any problems as values; the value for a successfully found module will be undef.
Modules are searched for in @$incdirs, defaulting to @INC.
verify_dependencies($meta,$phases,$types,$incdirs)
Check all requirements in $meta for phases $phases and type $type. Modules are searched for in @$incdirs,
defaulting to @INC. $meta should be a CPAN::Meta::Prereqs or CPAN::Meta object.
requirements_for($meta,$phases,$types)Thisfunctionisdeprecatedandmayberemovedatsomepointinthefuture,pleaseuseCPAN::Meta::Prereqs->merged_requirementsinstead.
This function returns a unified CPAN::Meta::Requirements object for all $type requirements for $phases.
$phases may be either one (scalar) value or an arrayref of valid values as defined by the CPAN::Meta
spec. $type must be a relationship as defined by the same spec. $meta should be a CPAN::Meta::Prereqs or
CPAN::Meta object.
