As per, https://www.isc.org/licenses/,
the ISC license may be used.

My apologies for the all caps garbage
that isn't easily readable in braille
or by screen readers.

Consider this license to be my
eternal blessing, birthrite, clone permission,
modification permission, etc.

If you need the ISC license or a
common license to use a work,
here it is.

Per my understanding, copyright is
implicit and need not be declared by 
the author.  As in works are copyrighted
irregardless of whether or not someone 
writes "copyright" blah blah whoever on them.

Therefore, all you need to know is
that the publisher of this module
included this text saying that this 
work can understood with the blessing
written below.

Sincerely,

The creator of this module


P.S.

If you have any problems with this,
please consider those to have absolutelly
zero to do with me, because I mostly
hate including a bunch of accessibility
unfriendly text.
