# config_vars.sh is generated by configure, and is run by the "install-build"
# target to generate a version of config_vars.mk which is suitable to be
# installed.  Such a file cannot be generated at configure-time, since it
# requires the output of the *installed* ap*-config scripts.

# For a DESTDIR=... installation using the bundled copies of 
# apr/apr-util, the installed ap?-config scripts must be found 
# in the DESTDIR-relocated install tree.  For a DESTDIR=... 
# installation when using *external* copies of apr/apr-util,
# the absolute path must be used, not DESTDIR-relocated.
