Branches: MAIN
CVS tags: version_2_12_X, version_2_11_X, version_2_11_4_uiuc, version_2_11_4_msu, version_2_11_4, version_2_11_3_uiuc, version_2_11_3_msu, version_2_11_3, version_2_11_2_uiuc, version_2_11_2_msu, version_2_11_2_educog, version_2_11_2, version_2_11_1, HEAD
- Avoid time-consuming recursion of user directories when running ./UPDATE
  to fix pre LON-CAPA 2.0 (and pre-2.2 in one case), which will have been
  fixed when library servers were updated to versions 2.2 through 2.10.
- No pre-2.2 instances currently in the production cluster.
