\n\
Usage: $PROGNAME [OPTION]...\n\
\n\
Examples:\n\
  $PROGNAME                 # simply run $PROGNAME in standard mode\n\
  $PROGNAME --simulate      # Simulates. doesn't really send sms (for debug)\n\
  echo \"Hello Beauty ;-)\" | $PROGNAME --smsset\n\
                          # Preset \"Hello Beauty ;-)\" as SMS message.\n\
  $PROGNAME --smsset < mymessage.txt\n\
                          # Preset contents of file mymessage.txt \n\
                            as SMS message.\n\
  $PROGNAME --version       # Display version, author and quits.\n\
\n\
NOTE:\n\
If you require to pickup number from phone's memory (really from SIM card),\n\
for the first time, it anyway reads phonebook from your cellular phone. \n\
(It may take a while... please, be patient ;-) \n\
\n\
Available options:\n\
  --debug, -D            May bother with more debugging messages ;-)\n\
                         For debugging purpose.\n\
  --simul[ate], -S       Simulation mode. Doesn't really send SMS by phone. \n\
                         Only simulates. For debugging purpose.\n\
  --forcememread, -F     Forces $PROGNAME to read phonebook from SIM card,\n\
                         and to parse the generated file in order to update\n\
                         the numbers' list (useful only if required to pickup\n\
                         number from the phone's memory). see NOTE.\n\
  --skipgnokiicheck, -K  Skip the test of the presence of binary 'gnokii'.\n\
                         (It must be somewhere in your \$PATH). It allows you\n\
                         to try this script program, even if you don't have\n\
                         'gnokii' already. ;)\n\
  --smsset, --setsms     Allows you to preset a SMS message from STDIN. (pipe\n\
                         or input redirection).\n\
                         This message will be proposed on the 'SMS message'\n\
                         field during the program input cycle.\n\
  --help, -h, /h         display this help and exit\n\
  --version, -V          output version information and exit"
