-- @usage set [ -s | -i | -b | -f | -t | -u ] parameter value
-- @summary set the value of a parameter
-- @start-doc
-- Set the value of a parameter. The options selects type: integer,
-- boolean, etc. or, for "-u" conditionally set the parameter only if it is
-- not already defined, i.e., provide fall-back values for parameters that
-- can be set on the command line.
--
-- Examples,
--
-- * Set a parameter to a string value, the "-s" is optional::
--
-- ZBTest> set SFO "San Francisco"
-- ZBTest> print SFO
-- San Francisco
-- ZBTest> set -s LLW Lilongwe
-- ZBTest> print LLW
-- Lilongwe
--
-- * Set a parameter to an integer value, the "-i" is required::
--
-- ZBTest> set -i ten 10
-- ZBTest> print ten
-- 10
--
-- * Set a parameter to a Boolean value, the "-b" is required::
--
-- ZBTest> set -b flag true
-- ZBTest> print flag
-- TRUE
--
-- * Set a parameter to a floating point value, the "-f" is required::
--
-- ZBTest> set -f pi 3.141592
-- ZBTest> print pi
-- 3.14159E+00
--
-- * Set a parameter to a time value, the "-t" is required. The only time
-- value supported is the special time "now"::
--
-- ZBTest> set -t start now
-- ZBTest> print start
-- 1:59 PM 11/21/16
--
-- * Set a parameter if not already defined, e.g., via the command line::
--
-- ZBTest> set -u -s build_opt ""
