Re: Conditionally process directives based on environment variable values in Apache conf?

I found this in the mail archives.

http://mail-archives.apache.org/mod_mbox/httpd-users/200601.mbox/%3Ce498c1660601190620i664df153y2bbbbd8f7aa2a9d7@xxxxxxxxxxxxxx%3E

"But the standard advice in cases like this is: httpd.conf is not a
programming language, it is a config file.  If you need more advanced
features, then use your favorite preprocess (m4, etc) to generate your
config files."

This certainly applies to my situation, and I was thinking something
similar.  Still, the Apache httpd conf syntax is quite powerful, so my
question still seemed worth asking.
