# Makefile modificator
#
# Should help in building bin/tests/system tests standalone,
# linked to libraries installed into the system.
# TODO:
# - Fix top_srcdir, because dyndb/driver/Makefile uses $TOPSRC/mkinstalldirs
# - Fix conf.sh to contain paths to system tools
# - Export $TOP/version somewhere, where it would be used
# - system tests needs bin/tests code. Do not include just bin/tests/system
#
# Possible solution:
#
# sed -e 's/$TOP\/s\?bin\/\(delv\|confgen\|named\|nsupdate\|pkcs11\|python\|rndc\|check\|dig\|dnssec\|tools\)\/\([[:alnum:]-]\+\)/`type -p \2`/' conf.sh
# sed -e 's,../../../../\(isc-config.sh\),\1,' builtin/tests.sh
# or use: $NAMED -V | head -1 | cut -d ' ' -f 2

Script for replacing Makefile ISC_INCLUDES with runtime flags.
