logtail binary package in Ubuntu Lunar s390x

 Each time logtail and logtail2 are run on a file they print lines
 added since the last run.
 .
 They can be used by log checkers, such as logcheck, to identify new
 entries in log files.
 .
 This package provides both logtail and logtail2. The latter is better
 suited to log files that may be rotated between runs: if logtail2
 finds that the inode of the file changed, it tries to find the file
 it was rotated from using customisable heuristics. If it finds the
 file, it will new find lines added to the old file as well as to the
 new file.
