This module verifies if requirements described in a CPAN::Meta object are present.

.el .SS "check_requirements($reqs, \f(CW$type\fP, \f(CW$incdirs\fP)"
.IX Subsection "check_requirements($reqs, $type, $incdirs)"
This function checks if all dependencies in \f(CW$reqs\fR (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 \f(CW@$incdirs\fR, defaulting to \f(CW@INC\fR.
.ie n .SS "verify_dependencies($meta, $phases, $types, $incdirs)"
.el .SS "verify_dependencies($meta, \f(CW$phases\fP, \f(CW$types\fP, \f(CW$incdirs\fP)"
.IX Subsection "verify_dependencies($meta, $phases, $types, $incdirs)"
Check all requirements in \f(CW$meta\fR for phases \f(CW$phases\fR and type \f(CW$type\fR. Modules are searched for in \f(CW@$incdirs\fR, defaulting to \f(CW@INC\fR. \f(CW$meta\fR should be a CPAN::Meta::Prereqs or CPAN::Meta object.

\&\fBThis function is deprecated and may be removed at some point in the future, please use CPAN::Meta::Prereqs\->merged_requirements instead.\fR
.PP
This function returns a unified CPAN::Meta::Requirements object for all \f(CW$type\fR requirements for \f(CW$phases\fR. \f(CW$phases\fR may be either one (scalar) value or an arrayref of valid values as defined by the CPAN::Meta spec. \f(CW$type\fR must be a relationship as defined by the same spec. \f(CW$meta\fR should be a CPAN::Meta::Prereqs or CPAN::Meta object.
