+// IEEE1800-2017 Clause 22.3
+// When `resetall compiler directive is encountered during compilation, all
+// compiler directives are set to the default values. This is useful for
+// ensuring that only directives that are desired in compiling a particular
+// source file are active.
+// The recommended usage is to place `resetall at the beginning of each source
+// text file, followed immediately by the directives desired in the file.
+// It shall be illegal for the `resetall directive to be specified within
+// a design element.
+// Not all compiler directives have a default value (e.g., `define and
+// `include). Directives that do not have a default are not affected by
+// `resetall.
