* configure.ac, Makefile.am: Descend into testsuite/ directory. Remove local test logic. * configure, Makefile.in: Regenerated. * runtest.sh: Not yet removed. * HACKING: Update for new testsuite layout. 2006-08-12 Frank Ch. Eigler <fche@elastic.org> * all: Reorganized old pass-1..4 tests one dejagnu bucket. Moved over old pass-5 tests, except for disabled syscalls tests. * Makefile (installcheck): New target for running pass-1..5 tests against installed systemtap.
