### Commentary:

## Extract all the @foo@ configuration symbols from ../configure
## to make them available to elisp later (see util/config.el)
## Primarily useful for creating ridiculously verbose bug reports.
## See lisp/utils/config.el, ../,
## and the Autoconf documentation on AC_OUTPUT, for more details.
## This script needs only to be run occasionally (before a Net release)
## by an XEmacs Maintainer (consider yourself so blessed, if you are
## actually reading this commentary).
