# serial 1

# The idea is to distribute rx.[hc] and regex.[hc] together, for a while.
# The WITH_REGEX symbol (which should also be documented in acconfig.h)
# is used to decide which of regex.h or rx.h should be included in the
# application.  If `./configure --with-regex' is given (the default), the
# package will use gawk's regex.  If `./configure --without-regex', a
# check is made to see if rx is already installed, as with newer Linux'es.
# If not found, the package will use the rx from the distribution.
# If found, the package will use the system's rx which, on Linux at least,
# will result in a smaller executable file.
