## Usage: shtool [<options>] [<cmd-name> [<cmd-options>] [<cmd-args>]]
##
## Available commands:
## install Install a program, script or datafile
## mkdir Make one or more directories
## mkshadow Make a shadow tree through symbolic links
##
## Not available commands (because module was not built-in):
## echo Print string with optional construct expansion
## mdate Pretty-print modification time of a file or dir
## table Pretty-print a field-separated list as a table
## prop Display progress with a running propeller
## move Move files with simultaneous substitution
## mkln Make link with calculation of relative paths
## fixperm Fix file permissions inside a source tree
## tarball Roll distribution tarballs
## guessos Simple operating system guesser
## arx Extended archive command
## slo Separate linker options by library class
## scpp Sharing C Pre-Processor
## version Maintain a version information file
## path Deal with program paths
