 Notes:
-before importing:
+As of April 2014, there are three versions of gcc in the NetBSD tree.
+In the long term, we expect that there will often be two versions,
+in the "gcc" and "gcc.old" directories.  Having two versions allows
+migration from one version of gcc to another to happen for one port
+at a time, instead of for all ports simultaneously.
+When importing a new version of external/gpl3/gcc.old:
+       - copy the current version of external/gpl3/gcc
+       - import it to a "NETBSD" vendor branch in externalgpl3/gcc.old
+Before importing a new version of external/gpl3/gcc:
        - delete all .cvsignore and .gitignore files
        - delete java ada fortran their libraries and testsuites
        - delete libffi zlib boehm-gc
