 *                        ENTRY
 *
 * We have to remove the keyword "section" from possible entry keywords
 * otherwise it would lead to an ambiguity with the "section" label
 * since PHP allows entries outside of sections.

(************************************************************************
 *                         TITLE
 *
 * We use IniFile.title_label because there can be entries
 * outside of sections whose labels would conflict with section names

(************************************************************************
 *                         LENS & FILTER
 * There can be entries before any section
 * IniFile.entry includes comment management, so we just pass entry to lns
