rm and files beginning with a dash

I could not remove a file whose name began with a dash (e.g. 
"-main-file.tmp").  (Hmmm  I suppose I could have tried "rm 
./-main-file.tmp".)  [Actually, I removed the file, but I used a Solaris 
tool to do the job instead of a GNU tool because the Solaris tool seemed 
easier to use.]

Solaris allows "rm - -main-file.tmp".

The Usage information for 'rm' quoted below suggests that "touch blah ; 
rm blah -main-file.tmp" might work (since it suggests that options and 
files can't be interspersed), but, of course, options and filenames can 
be interspersed.
