[tei-council] "right" way to locally build customization?

[Syd Bauman]

I used to use the command at
     https://svn.code.sf.net/p/tei/code/trunk/Roma/roma2.sh
to generate TEI customizations. Is there a new, better, or more
correct way to do that in the modern `ant` world? (And mean to 
build it locally w/o launching oXygen, not by using a web service.)
