# This is the script used to create the preferred-parent-cycle CVS
# repository.  (The repository is checked into svn; this script is
# only here for its documentation value.)
#
# The script should be started from the main cvs2svn directory.
#
# The branching structure of the three files in this repository is
# constructed to create a loop in the preferred parent of each branch
# A, B, and C.  The branches are as follows ('*' marks revisions,
# which are used to prevent trunk from being a possible parent of
# branches A, B, or C):
#
# file1:
# --*--+-------------------- trunk
#      |
#      +--*--+-------------- branch X
#            |
#            +-------------- branch A
#            |
#            +-------------- branch B
#            |
#            +-------------- branch C
#
# file2:
# --*--+-------------------- trunk
#      |
#      +--*--+-------------- branch Y
#            |
#            +-------------- branch B
#            |
#            +-------------- branch C
#            |
#            +-------------- branch A
#
# file3:
# --*--+-------------------- trunk
#      |
#      +--*--+-------------- branch Z
#            |
#            +-------------- branch C
#            |
#            +-------------- branch A
#            |
#            +-------------- branch B
#

# Note that the possible parents of A are (X, Y, Z, C*2, B*1), those
# of B are (X, Y, Z, A*2, C*1), and those of C are (X, Y, Z, B*2,
# A*1).  Therefore the preferred parents form a cycle A -> C -> B ->
# A.
