the 'tree' command for my little tcl utilities collection now pretty
prints, but is still valid data. format is { path { subdirectories }}

example output:

mush {{
mush/people.tcl {}} {
mush/player.tcl {}} {
mush/input.tcl {}} {
mush/notions.tcl {}} {
mush/mush.tcl {}} {
mush/c {{
mush/c/raymath.h {}} {
mush/c/raylib.h {}} {
mush/c/raygui.h {}} {
mush/c/libraylib.a {}} {
mush/c/rl.c {}} {
mush/c/make.tcl {}} {
mush/c/rlgl.h {}} {
mush/c/rl.so {}}}} {
mush/graphics.tcl {}} {
mush/tool.tcl {}} {
mush/tools.txt {}} {
mush/proto.tcl {}} {
mush/event.tcl {}} {
mush/object.tcl {}}}

last line in tree got wrapped for some reason, tclreadline isn't actually
needed (leftover from old interactive thing) and i forgot to remove it
