:-) In this case the svn command line client could be viewed as a library
for the script. (Which indeed means to imply that the APR versioning document
could be applicable.) :-)

Note that this schema for version numbering does not imply that a new minor
number contains new functionality. The new minor could also be a bugfix which
would not be satisfied by the 'forward and backward' compatibility
constraint. From an earlier post from you I concluded that to you a new minor number
implies new functionality.
