- # mh = mhlib.MH(mailbox) # override mailbox location (default from profile)
- # mh = mhlib.MH(mailbox, profile) # override mailbox and profile
- #
- # mh.error(format, ...) # print error message -- can be overridden
- # s = mh.getprofile(key) # profile entry (None if not set)
- # path = mh.getpath() # mailbox pathname
- # name = mh.getcontext() # name of current folder
