TRUNCLOG - Another FrontDoor LOG-file truncator...
Written by Erik Wachtmeester in Turbo Pascal (tm) 5.5.
Syntax: TRUNCLOG 
E.g.: TRUNCLOG C:\FD\FD.LOG 7 C:\FD\HIST\OLD.LOG
In this case, TRUNCLOG deletes all entries older than 7 days from your FD.LOG
in the directory C:\FD, and keeps the deleted entries in C:\FD\HIST\OLD.LOG.
The is optional, and in all cases, if no directory is given, the
current directory will be used. If already exists, the new deleted
entries will be appended to it, otherwise a new will be created.
TRUNCLOG checks the date by looking for entries like:
"---------- ddd DD mmm YY"
where "ddd" is the dayname (wich will be ignored), and "DD mmm YY" is the date
("D mmm YY" is also recognised in e.g. "9 jan 91"). The "----------" is
Programs that use this syntax for their logfiles include FrontDoor, TosScan,
MButil, FileFix, RA, and probably a lot more. Please check this with your own
