FUNCTIONS

       None of he following functions is exported by default.

       find_cpan_module
           Returns CPAN::Module object that corresponds to the supplied argument. Returns undef
           if no module is found by CPAN.

           If the CPAN module needs to be configured in some way, that should be done before
           calling this function.

       find_cpan_distribution
           Returns CPAN::Distribution object that corresponds to the supplied argument.  Returns
           undef if no distribution is found by CPAN.

           If the CPAN module needs to be configured in some way, that should be done before
           calling this function.

       is_core_module module, version
           Returns the version of the "perl" package containing the given module (at least
           version version).

           Returns "undef" if module is not a core module.

       nice_perl_ver version_string
           Re-formats perl version to match Debian's perl package versions.

           For example 5.010 (and 5.01) is converted to 5.10.

       core_module_perls module[, min-version]
           Returns a list of Perl versions that have module. If min-version is given, the list
           contains only Perl versions containing module at least version min-version.

       find_core_perl_dependency( $module[, $version] )
           return a dependency on perl containing the required module version. If the module is
           not available in any perl released by Debian, return undef.

       split_version_relation string
           Splits the string, typically found in dependency fields' values in CPAN META into
           relation and version. If no relation is found in the string, ">=" is assumed.

           Returns a list of relation and version. The relation is suitable for using in Debian
           package dependency version requirements.

           For example

           split_version_relation('0.45') returns ( '>=', '0.45' )
           split_version_relation('< 0.56') returns ( '<<', '0.56' )
