This filename, version number info is used to index an -# associative array. All of the files to be committed are checked to -# see if any locks are outstanding. If locks are outstanding, the -# version number of the current file (taken from the CVS/Entries -# subdirectory) is used in the key to determine if that version is -# locked.
