npm package.json field - man

Specify either a single file or an array of
filenames to put in place for the man program to
find.

If only a single file is provided, then it’s
installed such that it is the result from man
, regardless of its actual filename. For
example:

{
  "name": "foo",
  "version": "1.2.3",
  "description": "A packaged foo fooer for fooing foos",
  "main": "foo.js",
  "man": "./man/doc.1"
}

would link the ./man/doc.1 file in such that it is
the target for man foo
