This is a program/module for bringing a set of files under ClearCase control by making the minimal set of required changes and running the minimal set of cleartool operations. The real code is in the module, but a wrapper script 'synctree' is provided for command-line access. For those familar with 'citree', consider this a version of citree that works on both UNIX and Windows NT (citree is UNIX-only). Note: newer versions may be present at http://www.perl.com/CPAN-local/modules/by-module/IPC/DSB/.
