# This module is an over-engineered solution to a non-problem.

# shell alias system that organizes aliases into a tree structure,
# with categories and subcategories and subsubcategories and so on.
#
# It also has a lazy join function that will join a list of commands
# with a separator, but render it in a prettier way in a documentation
# file that you can print out and read.
