v0.22 to v0.26
--------------
     * I have added a Carrier lost detection after a
       Connect. This means that when you call a system and
       you get a bad connection and you lose the carrier
       Telcost will detect this from the LOG file and
       calculate the time you have been on-line and write it
       to the TELCOST.TXT file.

v0.26 to v0.50 (first public release)
--------------
     * Added some display so you can see what he is doing.
     * Added the PREMONTH option (See DOC)
     * Bugfix : When no FD.LOG file available Telcost went
       in a loop and you had to restart your computer.
