# Most of the test harness lives in a file hosttest.exp. This is part
# of the host-side infrastructure and gets installed in the directory
# $(PREFIX)/share/dejagnu. Other packages have to locate the file
# the hard way since the PREFIX is not provided automatically in
# the site.exp file, instead it is necessary to search through the
# build tree's Makefile. In the case of the infrastructure itself
# a shortcut is both possible and desirable because the script may
# not have been installed yet.
#
# Note that srcdir actually points at the testsuite subdirectory, not
# at the real srcdir.

# Now that the hosttest.exp utilities are available it is possible to do
# a bit more initialization. In particular it is possible to read in the
# build tree's Makefile and look for definitions of CC, CXX, and any
# other information from the Makefile that may prove useful.

# There are standard routines ${tool}_start, ${tool}_load, ${tool}_exit
# and ${tool}_version which test harnesses should normally implement.
# In practice runtest only invokes ${tool}_exit and ${tool}_version
# directly, the rest may or may not be invoked from inside the individual
# test scripts.
#
# ${tool}_version is relatively straightforward. The master version
# number is maintained in the configure.in script and is exported to
# the build tree's Makefile. There is a hosttest routine which does the
# hard work because getting the information is common to all host
# packages. The _version routine itself cannot be made completely generic
# because the first output is package-specific.

# routine.

}

# ${tool}_load is used to load a test case into the tool. The exact
# meaning is not applicable. However it makes sense to have this
# routine provide an alias for hosttest_run_simple_test which provides
# all the libraries etc. that are going to be needed.
