Hi,

Some of the error reporting for the options and ini settings could be 
better (Or work at all in this case. My yuqk fork misses the error 
too...). That last line above should have been:

Output_Alpha=on

   or

+ua

Here is a complete scene (use the default camera) showing the command 
line invocation to run it. It's set up for v3.7, but will work with v3.8 
releases too.

//--- this.pov
// Run with:
//      povray this.pov +ua +fn
// If running using an ini file the two key in options are:
//      Output_Alpha=on
//      Output_File_Type=N
#version 3.7;
background { rgbt <0,0,0,1> }
sphere {
     <0,0,2>, 0.2
     pigment { rgb <1,0,0> }
     finish { emission 1 }
}
//---

Aside: The options whether flag or ini formats can be used on either the 
command line or in ini files. Though, mostly, people stick to one method 
of specifying options.
