+ * JSON does not support regexes, so, e.g., JSON.parse() will not create
+ * a RegExp from the JSON value `[ "/matchString/" ]`, which is
+ * technically just an array containing a string that begins and end with
+ * a forward slash. To get a RegExp from a JSON string, it must be
+ * constructed explicitly in JavaScript.
+ *
+ * The likelihood of actually wanting to match text that is enclosed in
+ * forward slashes is probably quite rare, so if forward slashes were
+ * included in an argument that requires a regex, the user most likely
+ * thought they were part of the syntax for specifying a regex.
+ *
+ * In the unlikely case that forward slashes are indeed desired in the
+ * search string, the user would need to enclose the expression in a
+ * second set of slashes:
+ *
+ * --customAttrSrround "[\"//matchString//\"]"
