+HTMLUNWRAP(1)
+
+# NAME
+
+htmlunwrap - unwrap elements in an HTML document
+
+# SYNOPSIS
+
+*htmlunwrap* SELECTOR [_FILE_]...
+
+# DESCRIPTION
+
+Reads each file in sequence and removes all elements matching SELECTOR. The
+children of those elements will be added to their grandparents, thus unwrapping
+them from their previous parent element. Prints resulting documents to standard
+output. If no FILE is given or FILE is -, read standard input.
+
+If any FILE cannot be processed, a message prefixed with the FILE name will be
+written to standard error.
