Rewrite bundle (page 1015) so the script it creates takes an optional list of filenames as arguments. If one or more filenames are given on the command line, only those files should be re-created; otherwise, all files in the shell archive should be re-created. For example, suppose all files with the file- name extension .c are bundled into an archive named srcshell, and you want to unbundle just the files test1.c and test2.c. The following command will unbundle just these two files:

$ bash srcshell test1.c test2.c
