### 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.
