Except for tr, all of the below tools are tiny versions of what you'd usually find in an UNIX system
and lack a lot of functionality that enhances interactive use - for example, chmod.com only accepts octal modes
instead of friendlier syntax like a+x.
While these tools are generally meant to be used by the build process, you are free to use them as a way to avoid inconsistencies
with shell scripting utilities across different operating systems.
