During review of
DM-7891, jsick said he intends for the final LSST documentation to link all mentions of API components, and requested that a style rule concerning manual links (@ref) be removed from the draft style guidelines. Without such a rule, however, current documentation will have no links at all.
Since it would be simpler to not introduce the rule now than to request/approve its removal later, the best solution is to enable Doxygen's autolinking, removing the need for @ref tags. This change should not cause compatibility problems for existing documentation that uses @ref.
