+## `fixup.sh`: Automatically edit `.ec2.mak` to your settings
+
+The utility `fixup.sh` can be used when revising `.ec2.mak`.  The committed
+revisions have to have empty values for variables such as `SGI_WFH`, yet
+when running tests you need your actual values set.
+
+To get around this, edit `fixup.sh` to include your settings for `SGI_SFH`,
+`KEY`, and `LKEY`.  Then, after editing `.ec2.mak`, commit the file
+with empty values, then run `fixup.sh` to set the values correctly for
+your use.  Then test the file with these correct values.
