/tmp/toybox-clean$ ./toybox ls -l
usage: toybox [--long | --version | [command] [arguments...]]

With no arguments, shows available commands. First argument is
name of a command to run, followed by any arguments to that command.

--long Show path to each command
--version Show toybox version

To install command symlinks, try:
  for i in $(/bin/toybox --long); do ln -s /bin/toybox $i; done

toybox: Unknown option l
/tmp/toybox-clean$


looks like it works for individual commands though, just the
multiplexer is broken:

/tmp/toybox-clean$ ./generated/unstripped/md5sum -c
usage: md5sum [-b] [-c FILE] [FILE]...

Calculate md5 hash for each input file, reading from stdin if none.
Output one hash (32 hex digits) for each input file, followed by filename.

-b brief (hash only, no filename)
-c Check each line of FILE is the same hash+filename we'd output.

md5sum: Missing argument to -c
