checkout--Check out sources for editing
=======================================

   * Synopsis: checkout [options] modules...

   * Requires: repository.

   * Changes: working directory.

   * Synonyms: co, get

   Make 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 part of the command 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.  See modules.

   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 (see Global options.) is specified, the
`CVSREAD' environment variable is specified (*note Environment
variables::.), or a watch is in effect for that file (see Watches.).

   Running `checkout' on a directory that was already built by a prior
`checkout' is also permitted, and has the same effect as specifying the
`-d' option to the `update' command, that is, any new directories that
have been created in the repository will appear in your work area.
See update.

   For the output produced by the `checkout' command see *Note update
output::.
