<literal>Yet Another Configurations Container</literal>
(<acronym>Yaconf</acronym>) is a configurations container,
it parses <literal>INI</literal> files, and store the result
in PHP when PHP is started, the result lives with the
whole PHP lifecycle.
</para>
<para>
Yaconf stores all configurations as
interned string or immutable array, which means they are
not refcounted-able, thus when you retrieving configurations
from <acronym>Yaconf</acronym>, it could be considered as zero-copy, very fast.
</para>
<para>
Yaconf supports sections and sections
inheritance in <literal>INI</literal> files. If PHP is built as non-ZTS build,
Yaconf also supports automatically reloading after <literal>INI</literal> files
are changed.
</para>
<para>
Yaconf requires PHP 7.0 or greater.
</para>
