New in version 2.4.
[group_1]are hosts, members of the group.
childrenmodifier indicates that the section contains groups.
varsmodifier indicates that the section contains variables assigned to members of the group.
key=valuesyntax are interpreted as Python literal structure (strings, numbers, tuples, lists, dicts, booleans, None), alternatively as string. For example
var=FALSEwould create a string equal to ‘FALSE’. Do not rely on types set during definition, always make sure you specify type with a filter when needed when consuming the variable.
