* $Log: tools.c,v $
* Revision 1.14 1998/09/26 18:30:14 akool
* - quick and dirty Call-History in "-m" Mode (press "h" for more info) added
* - eat's one more socket, Stefan: sockets[3] now is STDIN, FIRST_DESCR=4 !!
* - Support for tesion)) Baden-Wuerttemberg Tarif
* - more Providers
* - Patches from Wilfried Teiken <wteiken@terminus.cl-ki.uni-osnabrueck.de>
* - better zone-info support in "tools/isdnconf.c"
* - buffer-overrun in "isdntools.c" fixed
* - big Austrian Patch from Michael Reinelt <reinelt@eunet.at>
* - added $(DESTDIR) in any "Makefile.in"
* - new Configure-Switches "ISDN_AT" and "ISDN_DE"
* - splitted "takt.c" and "tools.c" into
* "takt_at.c" / "takt_de.c" ...
* "tools_at.c" / "takt_de.c" ...
* - new feature
* CALLFILE = /var/log/caller.log
* CALLFMT = %b %e %T %N7 %N3 %N4 %N5 %N6
* in "isdn.conf"
* - ATTENTION:
* 1. "isdnrep" dies with an seg-fault, if not HTML-Mode (Stefan?)
* 2. "isdnlog/Makefile.in" now has hardcoded "ISDN_DE" in "DEFS"
* should be fixed soon
*
* Revision 1.13 1998/06/21 11:53:23 akool
* First step to let isdnlog generate his own AOCD messages
*
* Revision 1.12 1998/06/07 21:09:57 akool
* - Accounting for the following new providers implemented:
* o.tel.o, Tele2, EWE TEL, Debitel, Mobilcom, Isis, NetCologne,
* TelePassport, Citykom Muenster, TelDaFax, Telekom, Hutchison Telekom,
* tesion)), HanseNet, KomTel, ACC, Talkline, Esprit, Interoute, Arcor,
* WESTCom, WorldCom, Viag Interkom
*
* Code shamelessly stolen from G.Glendown's (garry@insider.regio.net)
* program http://www.insider.org/tarif/gebuehr.c
*
* - Telekom's 10plus implemented
*
* - Berechnung der Gebuehrenzone implementiert
* (CityCall, RegioCall, GermanCall, GlobalCall)
* The entry "ZONE" is not needed anymore in the config-files
*
* you need the file
* http://swt.wi-inf.uni-essen.de/~omatthes/tgeb/vorwahl2.exe
* and the new entry
* [GLOBAL]
* AREADIFF = /usr/lib/isdn/vorwahl.dat
* for that feature.
*
* Many thanks to Olaf Matthes (olaf.matthes@uni-essen.de) for the
* Data-File and Harald Milz for his first Perl-Implementation!
*
* - Accounting for all "Sonderrufnummern" (0010 .. 11834) implemented
*
* You must install the file
* "isdn4k-utils/isdnlog/sonderrufnummern.dat.bz2"
* as "/usr/lib/isdn/sonderrufnummern.dat"
* for that feature.
*
* ATTENTION: This is *NO* production-code! Please test it carefully!
*
* Revision 1.11 1998/05/06 14:43:27 paul
* Assumption about country codes always being 2 digits long fixed for the
* USA case (caused strncpy to be called with length -1; ouch).
*
* Revision 1.10 1998/04/09 19:15:45 akool
* - CityPlus Implementation from Oliver Lauer <Oliver.Lauer@coburg.baynet.de>
