# This text file contains records (1 per line) that describe svn
# filesystem paths that are the opening and closing source revisions
# for copies to tags and branches.  The format is as follows:
#
#     SYMBOL_ID SVN_REVNUM TYPE BRANCH_ID CVS_FILE_ID
#
# Where type is either OPENING or CLOSING.  The SYMBOL_ID and
# SVN_REVNUM are the primary and secondary sorting criteria for
# creating SYMBOL_OPENINGS_CLOSINGS_SORTED.  BRANCH_ID is the symbol
# id of the branch where this opening or closing happened (in hex), or
# '*' for the default branch.  CVS_FILE_ID is the id of the
# corresponding CVSFile (in hex).

# For example, if branch B's number is 1.3.0.2 in this CVS file, and
# this file's 1.3 is the latest (by date) revision among *all* CVS
# files that is a source for branch B, then the CVSRevision.id
# corresponding to this file at 1.3 would list at least the symbol id
# for branch B in its list.
