# ifup-ppp script for pppd-2.3.5 (with persist & demand options) ver 0.2
# Grzegorz Stanislawski <stangrze@open.net.pl>
# Features:
#  - since persist option is included to pppd it''s no need to do werid loops
#    ifup-ppp script. This also makes your logfile grow slower when Your link
#    is down.
#  - chat-ppp? file with script for chat is now parsed by shell, so You can
#    include in it shell variables (for example $PHONE, $USERNAME)
#    You can define any variable in ifcfg-ppp? file and use it in chat-ppp?
#    You only have to add it's name into DATAFORCHAT variable
#    Note, that chat-ppp file is now parsed by shell, so you have to escape
#    with "\" all shell special characters like \$;:)(& etc.
