+One-line Summary: Replace svn with git in carma section of Externals_CAM.cfg
+Github PR URL:
+
+Purpose of changes (include the issue number and title text for each relevant GitHub issue):
+  Point CAM to the CARMA_base github repository instead of the SVN repository.
+
+Describe any changes made to build system:
+
+Describe any changes made to the namelist:
+
+List any changes to the defaults for the boundary datasets:
+
+Describe any substantial timing or memory changes:
+
+Code reviewed by:
+
+List all files eliminated:
+
+List all files added and what they do:
+
+List all existing files that have been modified, and describe the changes:
+
+If there were any failures reported from running test_driver.sh on any test
+platform, and checkin with these failures has been OK'd by the gatekeeper,
+then copy the lines from the td.*.status files for the failed tests to the
+appropriate machine below.  All failed tests must be justified.

+Summarize any changes to answers, i.e.,
+- what code configurations:
+- what platforms/compilers:
+- nature of change (roundoff; larger than roundoff but same climate; new
+  climate):
+
+If bitwise differences were observed, how did you show they were no worse
+than roundoff?
+
+If this tag changes climate describe the run(s) done to evaluate the new
+climate in enough detail that it(they) could be reproduced, i.e.,
+- source tag (all code used must be in the repository):
+- platform/compilers:
+- configure commandline:
+- build-namelist command (or complete namelist):
+- MSS location of output:
+
+MSS location of control simulations used to validate new climate:
+
+URL for AMWG diagnostics output used to validate new climate:
