NAME

       Debian::Control::FromCPAN - fill debian/control from unpacked CPAN distribution

SYNOPSIS

	   my $c = Debian::Control::FromCPAN->new();
	   $c->discover_dependencies( { ... } );
	   $c->prune_perl_deps;

	   Debian::Control::FromCPAN inherits from L<Debian::Control>.

METHODS

       discover_dependencies( [ { options hash } ] )
	   Discovers module dependencies and fills the dependency fields in debian/control accordingly.

	   Options:

	   apt_contents
	       An instance of Debian::AptContents to be used when locating to which package a required module belongs.

	   dir The directory where the cpan distribution was unpacked.

	   intrusive
	       A flag indicating permission to use Module::Depends::Intrusive for discovering dependencies in case Module::Depends fails. Sinse
	       this requires loading all Perl modules in the distribution (and running their BEGIN blocks (and the BEGIN blocks of their
	       dependencies, recursively), it is recommended to use this only when dealing with trusted sources.

	   require_deps
	       If true, causes the method to die if some a package for some dependency cannot be found. Otherwise only a warning is issued.

	   verbose
	   wnpp_query
	       An instance of Debian::WNPP::Query to be used when checking for WNPP bugs of depeended upon packages.

	   Returns a list of module names for which no suitable Debian packages were found.

       find_debs_for_modules dep hash[, APT contents[, verbose ]]
	   Scans the given hash of dependencies ( module => version ) and returns matching Debian package dependency specification (as an instance
	   of Debian::Dependencies class) and a list of missing modules. Installed packages are searched first, then the APT contents, then the
	   perl core.

       prune_simple_perl_dep
	   Input:

	   dependency object
	       shall be a simple dependency (no alternatives)

	   (optional) build dependency flag
	       true value indicates the dependency is a build-time one

	   The following checks are made

	   dependencies on "perl-modules"
	       These are replaced with "perl" as per Perl policy.

	   dependencies on "perl-base" and build-dependencies on "perl" or "perl-base"
	       These are removed, unless they specify a version greater than the one available in "oldstable" or the dependency relation is not
	       ">=" or ">>".

	   Return value:

	   undef
	       if the dependency is redundant.

	   pruned dependency
	       otherwise. "perl-modules" replaced with "perl".

       prune_perl_dep
	   Similar to "prune_simple_perl_dep", but supports alternative dependencies.  If any of the alternatives is redundant, the whole
	   dependency is considered redundant.

       prune_perl_deps
	   Remove redundant (build-)dependencies on perl, perl-modules and perl-base.
