Hi all,
attached patch makes an attempt to announce the ABI-changes in the coarrays
library. Me being German always has difficulties to find a proper wording. So
please propose improvements.
Stupid question: How to I test this? The change looks good in my browser. Is
there a style checker, I don't see?
Regards,
Ande
