Hi folks !
Along with this mail i send you two little pieces of code which i found
extremely useful. The first is a patch to the install program. Since
install is used by many source-packages to install themselves, i thought
it would be nice if install keeps track of the installed programs. The
patch attached does this. It takes some information from install-time
and spills them to a log file.
The second program is a little bash-script which utilizies this log.
Ahh, please note that these are quick & dirty hacks. If you like them I
think it would be great if you implement their functionality in a one of
the next fileutils-releases.
Best regards
Joern Merkel
