It should be noted that although each subsystem has many subdirectories under it, there are no source or include files in the intermediate directories, but only in the leaf directories. All the actual work is done in the directories that are at the leaf levels of these subsystem directories. If you select one from this list, ccd will take you to the appropriate directory. If you type a file name that is not in the comet or common modules of CoMeT, ccd will not change your current directory and will output a brief error message. Once again, note that at this time, ccd only works for files that are in the comet or common modules.
Every user has a default sandbox.
If the user wishes to go to a different sandbox, ccd can be given the name of the sandbox as an optional argument. To achieve this, ccd needs additional arguments. When a user wants to go a sandbox of a different user, a sandbox must be supplied. The default sandbox of a different user is not used. A specified set of individual files, an entire directory of files or all files in every subdirectory under the current one may be checked out using this CoDE Tool.
