 /* 
+ * This is a very 'hacky' filesystem which is used just so 
+ * test two important features of the vfs code: (1) that
+ * you can load a shared library from a vfs, (2) that when
+ * copying files from one fs to another, the 'mtime' is
+ * preserved.
+ * 
+ * It reates any file in 'simplefs:/' as a real file, and
+ * artificially creates a real file on the fly which it uses
+ * to extract information from.  The real file is uses is
+ * whatever follows the trailing '/' (e.g. 'foo' in 'simplefs:/foo'),
+ * and that file is assumed to exist in the native pwd, and is
+ * copied over to the native temporary directory where it is
+ * accessed.
+ * 
+ * Please do not consider this filesystem a model of how
+ * things are to be done.  It is quite the opposite!  But, it
+ * does allow us to test two important features.
+ * 
+ * Finally: this fs can only be used from one interpreter.
