CVS
This is the Title of the Book, eMatter Edition

CVS_RSH
Used to set the program CVS calls to connect to a remote repository in ext
mode. The default program is rsh.
The rsh command is unacceptably insecure. You should avoid it
completely; use ssh instead.
CVS_SERVER
If connecting to a CVS server using rsh, this variable is used to determine
which program is started on the server side. In ext and server modes, this
defaults to cvs. When the repository is on the local system, this defaults to
the path to the CVS client program.
CVSWRAPPERS
May contain no more than one wrapper, as explained in “CVS Wrappers,”
earlier in this chapter.
HOME, HOMEPATH, HOMEDRIVE
Used to determine where the user’s home directory is, to enable CVS to
locate its files. On Unix, GNU/Linux, and related systems, only HOME is
used. On Windows systems, HOMEDRIVE and HOMEPATH are used.
Some Windows operating systems (Windows NT, 2000, and XP) set these
variables automatically. If yours doesn’t, HOMEDRIVE should be set to the
drive letter (e.g., C:), and HOMEPATH should be set to the path (e.g., \home\
arnold).
PATH
Used to locate any programs whose path is not compiled with the CVS
program. This variable is still used, but it is less important now that the rcs,
diff, and patch programs CVS uses are all distributed with CVS.
