##  example_sms.pl -- simple example script to send
##                    an SMS message via a web cgi
##                    Works with German pitcom powered free SMS sites 
##                    - find one and look at the page source to set the
##                      pitcom variables (see below)
##                    - note that pitcom checks the referer, thus you should
##                      take care to set the proper value 
##
##  NOTE: while the 'big names' have implemented measures to prevent
##        the use of automated scripts, and disallow such scripts
##        explicitely in their TOS (Terms of Service), this is not
##        neccesarily true for smaller websites.
##
##        An example for the latter are German websites providing free
##        SMS (to German nets only) powered by pitcom. 
##        With a suitable query, you may find such sites on (e.g.) Google.
##        At the time of the writing of this script, the sites I found did not
##        disallow the use of scripts, but check for yourself if you are
##        using this.
##
##  usage: example_sms.pl [NR]
##    <NR>    destination phone number
##    message is read from STDIN
