Cross-Platform 'zip' Compression Library. A replacement
    for the 'zip' function, that does not require any additional
    external tools on any platform.

Provides a mechanism for chaining commands with a
    new forward-pipe operator, %>%. This operator will forward a
    value, or the result of an expression, into the next function
    call/expression. There is flexible support for the type
    of right-hand side expressions. For more information, see
    package vignette.
    To quote Rene Magritte, "Ceci n'est pas un pipe."

Infrastructure for extended formulas with multiple parts on the
             right-hand side and/or multiple responses on the left-hand side
	     (see <DOI:10.18637/jss.v034.i01>).
