SYNOPSIS

           use DhMakePerl::Utils qw(is_core_module);

FUNCTIONS

       None of he following functions is exported by default.

       apt_cache
           Evaluate the creation of an AptPkg::Cache, and return it on success

       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_perl_package package
           Returns  true  value  if  the  given package is a core Perl package, i.e. one of "perl", "perl-base",
           "perl-modules-X.Y", "libperlX.Y", and "perl-xs-dev".

           Having this in a central routine makes it easier to add/remove packages in the list.

       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 (anymore) in the current "perl" release.

       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, or if it is not in the current perl anymore, 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' )
