# This scripts assumes it lives in the contrib directory of the egcs
# source tree, so it will find the testsuite tree from its location.
# If you move it elsewhere, or want to use another testsuite tree, you
# can override the defaults with --srcdir=/some/dir/egcs or
# --testsuite=/some/dir/egcs/gcc/testsuite.  If you specify
# --testsuite, --srcdir will be ignored; otherwise, `/gcc/testsuite'
# will be appended to the srcdir.

# You may specify where the binaries to be tested should be picked up
# from.  If you specify --prefix=/some/dir, gcc, g++ and g77 will be
# looked for at /some/dir/bin.  Each one may be overridden by
# specifying --with-gcc=/pathname/to/gcc, --with-g++=/pathname/to/g++
# and --with-g77=/pathname/to/g77.  If you specify --without-gcc,
# --without-g++ or --without-g77, the test for the specified program
# will be skipped.  By default, gcc, g++ and g77 will be searched in
# the PATH.

# An additional argument may specify --tmpdir=/some/dir; by default,
# temporaries will be stored in the current directory, where the log
# files will be stored.

# The script will interpret arguments until it finds one it does not
# understand.  The remaining ones will be passed to `runtest'.  A
# double-dash can be used to explicitly separate the arguments to
# `test_installed' from the ones to `runtest'.

# This script should be run in an empty directory; it will refuse to
# run if it finds a file named site.exp in the current directory.
