--- Comment #6 from Christopher Yeleighton <giecrilj at stegny dot 2a.pl> --- (In reply to Jonathan Wakely from comment #3) > I'm not sure why the comment on the primary template doesn't show up (maybe > doxygen is only interested in a definition) and adding comments to the > partial specialization doesn't show up in the generated HTML either. There is no comment as of <URL: https://gcc.gnu.org/onlinedocs/libstdc++/libstdc++-api.20210701.html/a00221_source.html#l02373 >, so there is nothing to show up, and neither was there any at <URL: https://gcc.gnu.org/onlinedocs/libstdc++/libstdc++-api-4.5/a00875_source.html#l00176 >.
