use cvs to manager the source in my projects, however, i am in trouble to revise the version after tag,
nomatter it is -r or -b.

once i revise some files in brach, it always echo up_to_date check fail, if the file was added later than import, else no affect to the revise file.

i wonder weather i can revise one file by
cvs -q ci -r tagxxxx

thanks for your tips,
