You can do it consecutively, or put all in a single import (if your
imports does not conflict). Be sure, that you use `ecosconfig resolve'.
`ecos.ecc' is just a text file, you can use sed, awk, etc. and of course
ownself CDL rules to manage the CDL options. If `ecosconfig resolve' is
a silent, it will mean that you did not break things.
