+
+This is a translatable XML Entity file.
+See doc-base/scripts/text-entities.php for details.
+
+Everything about acronyms resides in this file, as two kinds of
+entities:
+
+- Acronym definitions, entities named after the acronym itself
+  (for example &php;), which render the term wrapped in an
+  <acronym> tag;
+- Acronym expansions, entities named acronym.expansion.<term>,
+  where <term> is the exact text used inside <acronym> tags,
+  holding the expanded meaning of the term.
+
+Besides being collected by text-entities.php like any other
+entity file, this file is also read directly, as a plain XML
+document, by automated tools:
+
+- PhD loads it to generate the expansion tooltips of <acronym>
+  tags (see phd/phpdotnet/phd/Package/PHP/XHTML.php);
+- doc-base/scripts/qa/check-acronyms.php uses it to report
+  statistics about defined and used acronyms.
+
+Because of these direct uses, some extra restrictions apply:
+
+- The contents of acronym.expansion.* entities must be plain
+  text: no child XML elements;
+- No entity in this file may contain references to other
+  entities;
+- Entities that are not acronym definitions or expansions do not
+  belong in this file, and are ignored by the tools above.
+
+Both groups should be listed in alphabetical order.
