 A.9 checkout--Check out sources for editing
    * Synopsis: checkout [options] modules...
    * Requires: repository.
    * Changes: working directory.
    * Synonyms: co, get
    Create or update a working directory containing copies of the source
 files specified by MODULES.  You must execute `checkout' before using
 most of the other CVS commands, since most of them operate on your
 working directory.
    The MODULES are either symbolic names for some collection of source
 directories and files, or paths to directories or files in the
 repository.  The symbolic names are defined in the `modules' file.
    Depending on the modules you specify, `checkout' may recursively
 create directories and populate them with the appropriate source files.
 You can then edit these source files at any time (regardless of
 whether other software developers are editing their own copies of the
 sources); update them to include new changes applied by others to the
 source repository; or commit your work as a permanent change to the
 source repository.
    Note that `checkout' is used to create directories.  The top-level
 directory created is always added to the directory where `checkout' is
 invoked, and usually has the same name as the specified module.  In the
 case of a module alias, the created sub-directory may have a different
 name, but you can be sure that it will be a sub-directory, and that
 `checkout' will show the relative path leading to each file as it is
 extracted into your private work area (unless you specify the `-Q'
 global option).
    The files created by `checkout' are created read-write, unless the
 `-r' option to CVS ( Global options) is specified, the `CVSREAD'
 environment variable is specified ( Environment variables), or a
 watch is in effect for that file ( Watches).
    Note that running `checkout' on a directory that was already built
 by a prior `checkout' is also permitted.  This is similar to specifying
 the `-d' option to the `update' command in the sense that new
 directories that have been created in the repository will appear in
 your work area.  However, `checkout' takes a module name whereas
 `update' takes a directory name.  Also to use `checkout' this way it
 must be run from the top level directory (where you originally ran
 `checkout' from), so before you run `checkout' to update an existing
 directory, don't forget to change your directory to the top level
    For the output produced by the `checkout' command see  update
