# Test coarray support.
#
# For the compilation tests, all files are compiles with the
# option -fcoarray=single and with -fcoarray=lib
#
# For the link and execution tests, for -fcoarray=lib the
# libcaf_single library is linked. Additionally, with the
# required settings another CAF library is used.

# Load procedures from common libraries.

# If a testcase doesn't have special options, use these.
