Same as is equivalent in every way to:
\x
child
argument but in the opposite direction, e.g.:== Mammal
=== Bat
{tag=flying-animal}
=== Cat
== Flying animal
== Mammal
=== Bat
=== Cat
== Flying animal
{child=bat}
Naming rationale:So
parent
as the opposite of child is already taken to be then "main parent" via the "\H
parent
argument"- we could have renamed the
\H
child
argument totags
as in "this header tags that one", but it would be a bit confusingtags
vstag
child
vs tag
it is for now.You generally want to use
tag
instead of the \H
child
argument because otherwise some very large header categories are going to contain Huge lists of children, which is not very nice when editing.It is possible to enforce the
\H
child
argument or the \H
tag
argument in a given project with the lint
h-tag
option.
