def initialize fn

  ## maintain the mapping between people and aliases. for contacts without
  ## aliases, there will be no @a2p entry, so @p2a.keys should be treated
  ## as the canonical list of contacts.

  @p2a = {} # person to alias
  @a2p = {} # alias to person

#alias_for(person) ⇒ Object 



47
 
# File 'lib/sup/contact.rb', line 47

def alias_for person; @p2a[person] end

#contact_for(aalias) ⇒ Object

# File 'lib/sup/contact.rb', line 46

#contacts_with_aliases ⇒ Object 



28
 
# File 'lib/sup/contact.rb', line 28

def contacts_with_aliases; @a2p.values.uniq end

#drop_contact(person) ⇒ Object

this may not actually be called anywhere, since we still keep contacts around without aliases to override any fullname changes.
