   5 # Grzegorz Stanislawski <stangrze@open.net.pl>
   6 # Features:
   7 #  - since persist option is included to pppd it's no need to do werid loops
   8 #    ifup-ppp script. This also makes your logfile grow slower when Your link
   9 #    is down.
  10 #  - chat-ppp? file with script for chat is now parsed by shell, so You can
  11 #    include in it shell variables (for example $PHONE, $USERNAME)
  12 #    You can define any variable in ifcfg-ppp? file and use it in chat-ppp?
  13 #    You only have to add it's name into DATAFORCHAT variable
  14 #    Note, that chat-ppp file is now parsed by shell, so you have to escape
  15 #    with "\" all shell special characters like \$;:)(& etc.
