363 | Some of the less-frequently used features of L<DBIx::Class> have external |
364 | module dependencies on their own. In order not to burden the average user |
365 | with modules he will never use, these optional dependencies are not included |
366 | in the base Makefile.PL. Instead an exception with a descriptive message is |
367 | thrown when a specific feature is missing one or several modules required for |
368 | its operation. This module is the central holding place for the current list |
7e3dc46f |
369 | of such dependencies, for DBIx::Class core authors, and DBIx::Class extension |
370 | authors alike. |

407 | This method should be used by DBIx::Class packagers, to get a hashref of all |
408 | dependencies keyed by dependency group. Each key (group name) can be supplied |
