#       [ choose a provider based on the current date and bring up 
#         the ppp link.  Useful in Germany where certain providers
#         offer free service on Sundays and holidays, if you have the
#         XXL telephone plan. ]
#
#
# Usage:  ponxxl [ provider-name [ options ] ]
#
# This script can be used in place of "pon".  If a provider name is 
# specified explicitly, that provider is used.  Any additional
# options are passed to PPP.  

# If the program is invoked with no arguments,  the xxl provider 
# (see setting below) will be used if the current date is a Sunday or a 
# national holiday (bundeseinheitlicher Feiertag), otherwise the normal 
# provider (see setting below) will be used.

# Provider names (to be passed to ppp).  Change these two lines to 
# correspond to providers which you have configured for ppp.
