I am including the source and manual pages for three tools that can be
helpful when using RCS.

- Rcstell reports files checked out as locked and optionaly their lockers.
- Slist helps creating S-lists, for sets of files, or executables.
- Rcsclean removes all files that can be recreated by RCS.

I have used these scripts over some time and they function for the style of
work I do.  They have not been tested in other working environments.

X.SH DESCRIPTION
X.I Rcsclean
Xdeletes any files in the current directory that can be recreated
Xby checking out the latest version of the revision tree.
XIt is conservative in its approach, comparing only unlocked files ending in
X.I ,v
Xin the current and the
X.I './RCS'
Xdirectories against the working versions.
X.PP
XAny of the rm options can be given as options to
X.I rcsclean.
XIn particular the
X.B \-f
Xoption can be used to force the deletion of all files without 
Xasking and the
X.B \-i 
Xoption for interactive prompting before each deletion.
X.PP

X.TH SLIST 1 "Aug 7, 1989"
X.UC 4
X.SH NAME
Xslist \- display the names and revision numbers of RCS files
X.SH SYNOPSIS
X.B slist
X[
X.B \-h
X] file ...
X.br
X.SH DESCRIPTION
X.I Slist
Xprints the names and revision numbers of the files given as arguments.
X.PP
XThe
X.B \-h
Xoption prints the revision number of the latest file in the trunk,
Xthus an slist of the 
X.I head 
X(frontier) of the RCS tree is printed.  This is useful for comparing against
Xthe output of
X.I slist
Xfrom an executable to check that the latest revisions were indeed used.
X.PP
XIf the
X.B \-h
Xoption is not used then the file name arguments need be
Xworking or executable
Xfile names containing valid 
X.I Header
Xidentifiers.
X.SH EXAMPLES
XCreate an slist from an executable:
X.RS
X.nf
X.ft B
X% slist executable >executable.slist
X.ft R
X.RE
X.br
X.ne 4
XCompare the working files against the latest revisions:
X.RS
X.nf
X.ft B
X% slist -h RCS/*.c,v >latest.slist
X% slist *.c | diff - latest.slist
X.ft R
X.fi
X.RE
X.SH DIAGNOSTICS
XComplaints from ident for files not containing identifiers.
X.br
XComplaints from rlog about non-existing RCS files.
