Should contain the full pathname to the root of the CVS
source repository (where the RCS files are
kept). This information must be available to CVS for
most commands to execute; if $CVSROOT is not set,
or if you wish to override it for one invocation, you
can supply it on the command line: `cvs -d cvsroot
cvs_command...' Once you have checked out a working
directory, CVS stores the appropriate root (in
the file `CVS/Root'), so normally you only need to
worry about this when initially checking out a working
If $RCSBIN is not set, and no path is compiled
into CVS, it will use $PATH to try to find all
programs it uses.
Used to locate the directory where the `.cvsrc'
file, and other such files, are searched. On Unix, CVS
just checks for HOME. On Windows NT, the system will
set HOMEDRIVE, for example to `d:' and HOMEPATH,
for example to `\joe'. On Windows 95, you'll
probably need to set HOMEDRIVE and HOMEPATH yourself.
Specifies the external program which CVS connects with,
when :ext: access method is specified.
see section 2.9.2 Connecting with rsh.
Used in client-server mode when accessing a remote
repository using RSH. It specifies the name of
the program to start on the server side when accessing
a remote repository using RSH. The default value
is cvs. see section 2.9.2 Connecting with rsh
Used in client-server mode when accessing the server
via Kerberos, GSSAPI, or CVS's password authentication if the port is not
specified in $CVSROOT.
see section 2.9 Remote repositories
Used in client-server mode. If set, specifies the port
number to be used when accessing the RCMD demon on
the server side. (Currently not used for Unix clients).
Used for debugging only in client-server
mode. If set, everything sent to the server is logged
into `$CVS_CLIENT_LOG.in' and everything
sent from the server is logged into
Used only for debugging the server side in
client-server mode. If set, delays the start of the
server child process the specified amount of
seconds so that you can attach to it with a debugger.
For CVS 1.10 and older, setting this variable
prevents CVS from overwriting the `CVS/Root'
file when the `-d' global option is specified.
Later versions of CVS do not rewrite
`CVS/Root', so CVS_IGNORE_REMOTE_ROOT has no
Used under OS/2 only. It specifies the name of the
command interpreter and defaults to CMD.EXE.
Directory in which temporary files are located.
The CVS server uses
TMPDIR. See section A.4 Global options, for a
description of how to specify this.
Some parts of CVS will always use `/tmp' (via
the tmpnam function provided by the system).
On Windows NT, TMP is used (via the _tempnam
function provided by the system).
The patch program which is used by the CVS
client uses TMPDIR, and if it is not set, uses
`/tmp' (at least with GNU patch 2.1). Note that
if your server and client are both running CVS
1.9.10 or later, CVS will not invoke an external
