The test CVS repository used for these tests is derived from one in
cvs2svn's test suite.

+This repository is for testing the ability to group revisions
+correctly along tags and branches.  Here is its history:
+
+  1.  The initial import (revision 1.1 of everybody) created a
+      directory structure with a file named `default' in each dir:
+
+            ./
+              default
+              sub1/default
+                   subsubA/default
+                   subsubB/default
+              sub2/default
+                   subsubA/default
+              sub3/default
+
+  2.  Then tagged everyone with T_ALL_INITIAL_FILES.
+
+  3.  Then tagged everyone except sub1/subsubB/default with
+      T_ALL_INITIAL_FILES_BUT_ONE.
+
+  4.  Then created branch B_FROM_INITIALS on everyone.
+
+  5.  Then created branch B_FROM_INITIALS_BUT_ONE on everyone except
+      /sub1/subsubB/default.
+
+  6.  Then committed modifications to two files: sub3/default, and
+      sub1/subsubA/default.
+
+  7.  Then committed a modification to all 7 files.
+
+  8.  Then backdated sub3/default to revision 1.2, and
+      sub2/subsubA/default to revision 1.1, and tagged with T_MIXED.
+
+  9.  Same as 8, but tagged with -b to create branch B_MIXED.
+
+  10. Switched the working copy to B_MIXED, and added
+      sub2/branch_B_MIXED_only.  (That's why the RCS file is in
+      sub2/Attic/ -- it never existed on trunk.)
+
+  11. In one commit, modified default, sub1/default, and
+      sub2/subsubA/default, on branch B_MIXED.
+
+  12. Did "cvs up -A" on sub2/default, then in one commit, made a
+      change to sub2/default and sub2/branch_B_MIXED_only.  So this
+      commit should be spread between the branch and the trunk.
+
+  13. Do "cvs up -A" to get everyone back to trunk, then make a new
+      branch B_SPLIT on everyone except sub1/subsubB/default,v.
+
+  14. Switch to branch B_SPLIT (see sub1/subsubB/default disappear)
+      and commit a change that affects everyone except sub3/default.
+
+  15. An hour or so later, "cvs up -A" to get sub1/subsubB/default
+      back, then commit a change on that file, on trunk.  (It's
+      important that this change happened after the previous commits
+      on B_SPLIT.)
+
+  16. Branch sub1/subsubB/default to B_SPLIT, then "cvs up -r B_SPLIT"
+      to switch the whole working copy to the branch.
+
+  17. Commit a change on B_SPLIT, to sub1/subsubB/default and
+      sub3/default.
