-.Sh NAME
-.Nm sccs
-.Nd front end for the
-.Li SCCS
-subsystem
-.Sh SYNOPSIS
-.Nm sccs
-.Op Fl r
-.Op Fl d Ar path
-.Op Fl p Ar path
-.Ar command
-.Op flags
-.Op Ar
-.Sh DESCRIPTION
-.Nm Sccs
-is a front end to the
-.Li SCCS
-programs
-that
-helps them mesh more cleanly
-with
-the rest of UNIX.
-It
-also includes the capability to run
-.Dq set user id
-to another user
-to
-provide additional protection.
-.Pp
-Basically,
-.Nm sccs
-runs the command with the specified
-.Ar flags
-and
-.Ar args .
-Each argument is normally modified to be prepended with
-.Dq Li SCCS/s. .
-.Pp
-Flags to be interpreted by the
-.Nm sccs
-program must be before the
-.Ar command
-argument.
-Flags to be passed to the actual
-.Li SCCS
-program must come after the
-.Ar command
-argument.
-These flags are specific to the command and
-are discussed in the documentation for that command.
-.Pp
-Besides the usual
-.Li SCCS
-commands,
-several
-.Dq pseudo-commands
-can be issued.
-These are:
-.Bl -tag -width deledit
-.It Cm edit
-Equivalent
-to 
-.Dq Li get \-e .
-.It Cm delget
-Perform a delta on the named files and
-then get new versions.
-The new versions will have id keywords expanded, and
-will not be editable.
-The
-.Fl m ,
-.Fl p ,
-.Fl r ,
-.Fl s ,
-and
-.Fl y
-flags will be passed to
-.Nm delta ,
-and the 
-.Fl b,
-.Fl c ,
-.Fl e ,
-.Fl i ,
-.Fl k ,
-.Fl l ,
-.Fl s ,
-.\" anybody who has a bad xterm which is almost anyone
-and
-.Fl x
-flags will be passed to get.
-.It Cm deledit
-Equivalent
-to
-.Nm delget
-except that the
-.Nm get
-phase includes the
-.Fl e
-flag.
-This
-option is useful for making a
-.Em checkpoint
-of your current editing phase.  The same flags will be passed to delta
-as described above, and
-all the flags listed for
-.om get
-above except
-.Fl e
-and
-.Fl k
-are
-passed to
-.Nm edit .
-.It Cm create
-Creates
-an
-.Li SCCS
-file ,
-taking
-the initial contents from the file of the same name.
-Any
-flags to
-.Nm admin
-are accepted.  If the creation is successful,
-the files are renamed with a comma on the front.
-These should be removed when you are convinced that the
-.Li SCCS
-files
-have been created successfully.
-.It Cm fix
-Must
-be followed by a
-.Fl r
-flag.
-This command essentially removes the named delta, but
-leaves you with a copy of the delta
-with the changes that were in it.  It
-is useful for fixing small compiler bugs, etc.
-Since it doesn't leave audit trails, it should be used carefully.
-.It Cm clean
-This routine removes everything from the current directory
-that can be recreated from SCCS files.
-It will not remove any files being edited.
-If the
-.Fl b
-flag is given, branches are ignored in the determination of
-whether they are being edited; this
-is dangerous if you are keeping the branches in the
-same directory.
-.It Cm unedit
-This
-is the opposite of an
-.Nm edit
-or
-a
-.Dq Li get \-e .
-It should be used with extreme caution, since
-any changes you made since the get will be irretrievably lost.
-.It Cm info
-Gives a listing of all files being edited.
-If the
-.Fl b
-flag
-is given, branches (i.e.,
-.Li SID Ns \&\'s 
-with two or fewer components)
-are ignored.  If the
-.Fl u
-flag is given (with an optional argument) then
-only files being edited by you (or the named user) are listed.
-.It Cm check
-Like
-.Nm info
-except that nothing is printed if nothing is being edited, and
-a non-zero exit status is returned if anything is being edited.
-The intent is to have this included in an
-.Em install
-entry in a makefile to insure that everything is included into the
-.Li SCCS
-file before a version is installed.
-.It Cm tell
-Gives a newline-separated list of the files being edited
-on the standard output.  Takes the
-.Fl b
-and
-.Fl u
-flags like
-.Nm info
-and
-.Nm check .
-.It Cm diffs
-Gives a
-.Nm diff
-listing between the current version of the
-program(s) you have out for editing and the versions in
-.Li SCCS
-format.
-The
-.Fl r ,
-.Fl c ,
-.Fl i ,
-.Fl x ,
-and
-.Fl t
-flags are passed to
-.if n \{\
-.	br
-.\}
-.Nm get ;
-the
-.Fl l ,
-.Fl s ,
-.Fl e ,
-.Fl f ,
-.Fl h ,
-and
-.Fl b
-options are passed to
-.if n \{\
-.	br
-.\}
-.Nm diff .
-The
-.Fl C
-flag is passed to
-.Nm diff
-as
-.Fl c .
-.It Cm print
-This command prints out verbose information
-about the named files.
-.Pp
-.It Fl r
-Runs
-.Nm sccs
-as the real user rather than as whatever effective user
-.Nm sccs
-is
-.Dq Li set user id
-to.
-.It Fl d
-Specifies a root directory for the
-.Li SCCS
-files.
-The default is the current directory.
-If environment variable
-.Ev PROJECT
-is set,
-it will be used to determine the 
-.Fl d
-flag.
-.It Fl p
-Defines the pathname of the directory in which the
-.Li SCCS
-files will be found;
-.Dq Li SCCS
-is the default.
-The
-.Fl p
-flag
-differs from the
-.Fl d
-flag
-in that the
-.Fl d
-argument is prepended to the entire pathname and the
-.Fl p
-argument is inserted before the final component of the pathname.
-For example,
-.Dq Li sccs \-d/x \-py get a/b
-will convert to
-.Dq Li get /x/a/y/s.b .
-The intent here is to create aliases such as
-.Dq Li alias syssccs sccs -d/usr/src
-which
-will be used as
-.Dq Li syssccs get cmd/who.c .
-.Pp
-Certain
-commands (such as
-.Nm admin  )
-cannot be run
-.Dq Li set user id
-by all users, since this would allow anyone to change the authorizations.
-These commands are always run as the real user.
-.Sh EXAMPLES
-To get a file for editing,
-edit it,
-and produce a new delta:
-.Pp
-.Dl sccs get \-e file.c
-.Dl ex file.c
-.Dl sccs delta file.c
-.Pp
-To get a file from another directory:
-.Pp
-.Dl sccs \-p/usr/src/sccs/s. get cc.c
-.Pp
-or
-.Pp
-.Dl sccs get /usr/src/sccs/s.cc.c
-.Pp
-To make a delta of a large number of files
-in the current directory:
-.Pp
-.Dl sccs delta *.c
-.Pp
-To get a list of files being edited that are not on branches:
-.Pp
-.Dl sccs info \-b
-.Pp
-To delta everything being edited by you:
-.Pp
-.Dl sccs delta \`sccs tell \-u\`
-.Pp
-In a makefile, to get source files
-from an
-.Li SCCS
-file if it does not already exist:
-.Pp
-.Dl SRCS = <list of source files>
-.Dl $(SRCS):
-.Dl \&\tsccs get $(REL) $@
-.Sh ENVIRONMENT
-.Bl -tag -width Ar
-.It Ev PROJECT
-The PROJECT environment variable is checked by the
-.Fl d
-flag.  If
-it begins with a slash, it is taken directly; otherwise,
-the home directory of a user of that name is
-examined for a subdirectory
-.Dq Li src
-or
-.Dq Li source .
-If such a directory is found, it is used.

-.Sh HISTORY
-The
-.Nm sccs
-command
-appeared in
-.Bx 4.3 .
-.Sh BUGS
-It should be able to take directory arguments on pseudo-commands
-like the
-.Li SCCS
-commands do.
