If you have two versions of TeX installed in different places, you can switch between them by changing the executable search path. The default is to find texmf.cnf relative to the binaries, so if you install under /usr/local and add the binaries directory to your PATH variable you will end up using the correct pool files. If you want to go back to the old configuration (e.g., because you have a large document that would need changes to work with the new version) you just set the PATH variable back. You can also set TEXMFCNF to override the default (e.g., if you want to use pdftex installed in a non-standard location, but keep the other binaries from an earlier installation). -- George White <[EMAIL PROTECTED]> Halifax, Nova Scotia
