=head1 NAME
stbuLog.pl - multiplex log files.
=head1 SYNOPSIS
stbuLog.pl [-r inFile] [-o outFile
[[-n noFiles] | [-s [-c compressprog]] ]
]
=head1 OPTIONS
=over 8
=item B<-o>, B<--out>
write output to file
=item B<-m>, B<--maxFilelen>
maximal len of file written round (default = 1e6)
=item B<-n>, B<--noOfOldFiles>
number of old files to store
=item B<-s>, B<--saveLogs>
save log files with date and time instead of deleting the
old (with [-noOfOldFiles])
=item B<-c>, B<--compressWith>
compress saved log files (e.g. with -c 'gzip -9')
