<p>Below is the BNF grammar for configuration files. Comments and include
directives are not part of the grammar, so they are not included here.
<p>Various open-source libraries have been written that provide access to
<i>libconfig</i>-style configuration files from other programming languages. Some
of these libraries are wrappers which add new language bindings for
<i>libconfig</i> while others are syntax-compatible reimplementations in other
languages.
