[texhax] Help with user fonts

[John A. Dundas III]

All,

 From a previous Unix installation of TeX, I have my own .pfb's, 
psfonts.map, dvips prologues, tex inputs, etc., files that I would 
like to retain and use.

I have installed TeX 9/2003 in its default configuration on my Mac OS 
X 10.2.8 system.  The default TeX appears to work correctly.

My question is: how do I override the TeX defaults for the above 
files?  I'm sure it's in the documentation, but I can't seem to find 
it.  I would think there are a few environment variables I could set 
that would name user-local directories to be searched before the 
system defaults.  Is it that simple?  Could you provide examples or 
pointers to the relevant documentation?

Thanks,

John
