module Puppet::Parser::Functions
newfunction(:validate_bool, :doc => <<-'ENDHEREDOC') do |args|
Validate that all passed values are either true or false. Abort catalog
compilation if any value fails this check.
The following values will pass:
$iamtrue = true
validate_bool(true)
validate_bool(true, true, false, $iamtrue)
The following values will fail, causing compilation to abort:
$some_array = [ true ]
validate_bool("false")
validate_bool("true")
validate_bool($some_array)
