newfunction(:any2bool, :type => :rvalue, :doc => <<-EOS
This converts 'anything' to a boolean. In practise it does the following:
* Strings such as Y,y,1,T,t,TRUE,yes,'true' will return true
* Strings such as 0,F,f,N,n,FALSE,no,'false' will return false
* Booleans will just return their original value
* Number (or a string representation of a number) > 0 will return true, otherwise false
* undef will return false
* Anything else will return true
