Mm, guess it depends on whose crontab you're using. Dillon's cron
has:

$ crontab -h
crontab 2.3.3
crontab file <opts>  replace crontab from file
crontab -    <opts>  replace crontab from stdin
crontab -u user      specify user
crontab -l [user]    list crontab for user
crontab -e [user]    edit crontab for user
crontab -d [user]    delete crontab for user
crontab -c dir       specify crontab directory

Vixie cron has:

$ crontab -h
crontab: invalid option -- h
crontab: usage error: unrecognized option
usage:  crontab [-u user] file
        crontab [-u user] { -e | -l | -r }
                (default operation is replace, per 1003.2)
        -e      (edit user's crontab)
        -l      (list user's crontab)
        -r      (delete user's crontab)
