 * will have to configure your RCS V5 release separately to make this
 * the case. If you do not have RCS V5 and GNU diff V1.15, comment out
 * this define. You should not try mixing and matching other
 * combinations of these tools.

 * that unlike the diff used with RCS, you *must not* supply -a here
 * (doing so will cause the server to generate patches which patch
 * cannot handle in some cases).
 *
 * NOTE: this program is only used for the ``patch'' sub-command (and
 * for ``update'' if you are using the server).  The other commands
 * use rcsdiff which will use whatever version of diff was specified
 * when rcsdiff was built on your system.

/*
 * By default, RCS programs are executed with the shell or through
 * execlp(), so the user's PATH environment variable is searched.  If
 * you'd like to bind all RCS programs to a certain directory (perhaps
 * one not in most people's PATH) then set the default in RCSBIN_DFLT.
 * Note that setting this here will cause all RCS programs to be
 * executed from this directory, unless the user overrides the default
 * with the RCSBIN environment variable or the "-b" option to CVS.
 *
 * If you use the password-authenticating server, then you need to
 * make sure that the server can find the RCS programs to invoke them.
 * The authenticating server starts out running as root, and then
 * switches to run as the appropriate user once authentication is
 * complete.  But no actual shell is ever started by that user, so the
 * PATH environment variable may not contain the directory with the
 * RCS binaries, even though if that user logged in normally, PATH
 * would include the directory.
 *
 * One way to solve this problem is to set RCSBIN_DFLT here.  An
 * alternative is to make sure that root has the right directory in
 * its path already.  Another, probably better alternative is to
 * specify -b in /etc/inetd.conf.
 *
 * You may also have to set RCSBIN_DFLT here if there's no global
 * start-up script run for users by rshd and your RCS programs are not
 * in a directory in the default PATH assigned by rshd.
 *
 * This define should be either the empty string ("") or a full
 * pathname to the directory containing all the installed programs
 * from the RCS distribution.

/* Define this to enable the SETXID support.  The way to use this is
   to create a group with no users in it (except perhaps cvs
   administrators), set the cvs executable to setgid that group, chown
   all the repository files to that group, and change all directory
   permissions in the repository to 770.  The last person to modify a
   file will own it, but as long as directory permissions are set
   right that won't matter.  You'll need a system which inherits file
   groups from the parent directory (WARNING: using the wrong kind of
   system (I think Solaris 2.4 is the wrong kind, for example) will
   create a security hole!  You will receive no warning other than the
   fact that files in the working directory are owned by the group
   which cvs is setgid to).

   One security hole which has been reported is that setgid is not
   turned off when the editor is invoked--most editors provide a way
   to execute a shell, or the user can specify an editor (this one is
   large enough to drive a truck through).  Don't assume that the
   holes described here are the only ones; I don't know how carefully
   SETXID has been inspected for security holes.  */

 * doesn't try to guarantee that anyway.  The master server process
 * will monitor how far it is getting behind, if it reaches the high
 * water mark, it will signal the child process to stop generating
 * data when convenient (ie: no locks are held, currently at the
 * beginning of a new directory).  Once the buffer has drained
