Last change on this file since ec550f7 was ec550f7, checked in by Mei <mei@…>, 6 years ago

1) reworked how API doc is generated
2) tweak top level Makefile.am
3) loading issuer principal as side-effect of loading

an attribute credentials

4) add examples of GENI specific attribute credentials

and principal certificates into the regression testing

5) rename examples to tests
