This version of the [unlink] utility is implemented from scratch. While barebones,
it should include all required functionality to be compatible in a scripting
environment.
Key differences from GNU [unlink]:
Does not accept __long__options__ and therefore no --help message. It
accepts the [-h] switch, printing only a terse usage statement, which is
also printed in the event of calling with incorrect syntax.
Supports the [-v] switch, in which case it reports back on the file(s)
being removed.
Multiple files can be specified and removed in a single command.
