+Utility Modules
+===============
+
+To ensure there are no external dependencies (including chicken eggs),
+these modules re-implement any basic procedures which are required for
+any algorithms used. And some advanced yet generic functionality as
+well.
+
+The modules are listed in alphabetical order.
+
+### CSV
+
+This module provides a very simple, incomplete and incorrect but fast
+CSV loader.
+
+    (csv-parse filename
+		[#:separator #\;]
+		[#:string-delimiter #\"])
+
+* ```separator``` - cell separator in CSV file
+* ```string-delimiter``` - for introducing strings possibly with separators
+
+Parses given CSV file and returns list of lists of strings
+representing its contents.
+
+    (csv-split-header csv)
+
+* ```csv``` - list of lists of strings
+
+Splits given loaded CSV into two tables at the first empty row.
+
+### IO
+
+### List
+
+    (import util-list)
+
+This module implements basic list functionality which is common in
+most scheme implementations.
+
+    (filter pred? lst)
+
+* ```pred?``` - procedure accepting any value and returning #t or #f
+* ```lst``` - list to be filtered
+
+Returns a list containing only elements matching given ```pred?```
+predicate.
+
+### Set (List)
+
+### String
+
+    (import util-string)
+
+String manipulation functions which are used throughout other modules.
+
+    (string-repeat str rep)
+
+* ```str``` - string to repeat
+* ```rep``` - number of repeats
+
+Returns a string created by repeating the string ```str``` exactly
+```rep``` number of times.
+
+    (string-first+rest str)
+
+* ```str``` - a string to split
+
+Returns a pair of strings where the ```car``` of the pair is the first
+token in the ```str``` given and ```cdr``` is a string with the
+remainder with leading whitespace removed.
