+// Pathname - parsing of pathnames into components, and vice versa.
+//
+// To establish consistent terminology, a filename never contains a folder
+// component. A folder never contains a filename. A pathname may include
+// a folder and/or filename component. Here are some examples:
+//
+// pathname() /home/john/example.txt
+// folder() /home/john/
+// filename() example.txt
+// parent_folder() /home/
+// folder_name() john/
+// basename() example
+// extension() .txt
+//
+// Basename may begin, end, and/or include periods, but no folder delimiters.
+// If extension exists, it consists of a period followed by zero or more
+// non-period/non-delimiter characters, and basename is non-empty.
