+* Sort SD file listings in alphabetical order.
+*
+* With this option enabled, items on SD cards will be sorted
+* by name for easier navigation.
+*
+* By default...
+*
+*  - Use the slowest -but safest- method for sorting.
+*  - Folders are sorted to the top.
+*  - The sort key is statically allocated.
+*  - No added G-code (M34) support.
+*  - 40 item sorting limit. (Items after the first 40 are unsorted.)
+*
+* SD sorting uses static allocation (as set by SDSORT_LIMIT), allowing the
+* compiler to calculate the worst-case usage and throw an error if the SRAM
+* limit is exceeded.
+*
+*  - SDSORT_USES_RAM provides faster sorting via a static directory buffer.
+*  - SDSORT_USES_STACK does the same, but uses a local stack-based buffer.
+*  - SDSORT_CACHE_NAMES will retain the sorted file listing in RAM. (Expensive!)
+*  - SDSORT_DYNAMIC_RAM only uses RAM when the SD menu is visible. (Use with caution!)
