-/**
- *  a simple facility for minimal programs or system libraries
- *  with no libc available at the time of invocation, as well
- *  as applications using the midipix free-standing development
- *  environment.
- *
- *  the approach taken by this module to the support of short
- *  and long options reflects the above constraint, namely
- *  the absence of a callable libc at the time of invocation;
- *  there is no intent for interfaces in this module to
- *  be POSIXLY correct or otherwise portable.  the sole
- *  purpose of all functions in this module is to serve
- *  internal or otherwise free-standing midipix applications,
- *  and their relevance otherwise is accordingly non-existent.
- *
- *  all options are encoded in utf-16; note, however, that
- *  short options may only use code points that are located
- *  in the basic multilingual plane.
- *
- *  option values are either required or not allowed altogether,
- *  and the first character of an option value may not be a hyphen.
- *  if you need the first character of an option value to be a
- *  hyphen, then make sure you escape it somehow (for instance by
- *  enclosing it in quotation marks).
- *
- *  a short option and its value must reside in two separate
- *  argv[] elements (in other words: -ooutput is illegal).
- *
- *  a long option and its value must reside in the same argv[]
- *  element and be separated by a single equal sign.
- *
- *  Examples of valid options and option values:
- *  --------------------------------------------
- *  -o
- *  -o value
- *  --long-option-with-no-value
- *  --long-option=value
