[+NAME?filetree1 - file tree demo]
[+DESCRIPTION?\bfiletree1\b is a small ksh93 compound variable demo
which accepts a directory name as input, and then builds tree
nodes for all files+directories and stores all file attributes
in these notes and then outputs the tree in the format
specified by viewmode (either "list", "namelist", "tree" or "compacttree")..]
