+### Mark and recall
+#
+# Jan Petykiewicz 2017-01-26
+#
+# Functions:
+#   mark : Mark a path for later recall.
+#          If no directory is given as an argument, marks the current working directory.
+#   mlist : List marked directories.
+#           Entries are unique and sorted most-to-least recent by mark time.
+#   recall: Return to a previously-marked directory.
+#           Pass a number to specify an entry in mlist; default is 1 (most recently marked).
+#   bamf: Return to a marked directory using a fuzzy search, e.g.
+#          ```bamf proj``` may match /home/username/projects/
+# 
+#   Use of bamf requires python3 and fuzzywuzzy.
