Help using rlog

[Kirsten Jones]

Folks,

I'm using rlog to grab file dates.  We have labels with dashes
in them, and I'm encountering the following problem with
rlog (the same version works fine with co, but I can't figure
out how to get it to deal with it in rlog).

people% /router/bin/rlog -rEFR-00000004147 
/nfs/acmecontrol/lineups/ios_ena/default.lu
rlog: warning: `-' is obsolete in `-rEFR-00000004147'; use `:' instead
rlog: /nfs/acmecontrol/lineups/ios_ena/RCS/default.lu,v: Symbolic name 
`EFR' is undefined.

Is there an escape character I can use to escape the dash?  Or
a substitution character?  Or am I just not going to be able to
check the dates on versions with dashes?

Thanks,
