	Is there any way to query kpathsea to find out what environment 
variables it knows about?  I'm trying to write some software that 
interacts with pdfTeX, etc. and it would be useful to know which 
environment variables the user provides will be significant when 
executing kpathsea aware programs as subprocesses.  Thanks!
