the script accepts an mtree file in a format that's returned by mtree -c | mtree -C

• -a prints all scan results. this is the default option if no option is provided.
• -c lints the file and gives warnings/errors, including duplication and conflicting metadata
  • -Wcheck-notagdir entries with dir type and no tags will be also included the first time they appear (1)
• -p list all package names found in the file as exactly specified by tags=package=...

• metalog_reader.lua -c -Wcheck-notagdir METALOG prints errors and warnings found in the file, including directories with no tags
• metalog_reader.lua -p METALOG only prints all the package names found in the file
• metalog_reader.lua -p -count -size METALOG prints all the package names, followed by number of files, followed by total size
• metalog_reader.lua -p -size -fsetid METALOG prints packages that has either setuid/setgid files, followed by the total size
• metalog_reader.lua -p -fsetuid -fsetgid METALOG prints packages that has both setuid and setgid files (if more than one filters are specified, they are composed using logic and)
• metalog_reader.lua -p -count -size -fsetuid METALOG prints packages that has setuid files, followed by number of files and total size

(1) if we have two entries

./bin type=dir uname=root gname=wheel mode=0755
./bin type=dir uname=root gname=wheel mode=0755 tags=...

by default, this is not warned. if the option is enabled, this will be warned as the second line sufficiently covers the first line.
