Oh, it actually does if  you ask it nicely by using the -F switch, which 
does uses the pkgdb to look up pkgnames from filenames, and then operates 
as usual. The following example tells you what /usr/pkg/bin/tcsh 
belongs to:

 	miyu% pi -Fe /usr/pkg/bin/tcsh
 	tcsh-6.13.00


And this lists all the files that belong to the same package that 
/usr/pkg/bin/tcsh belongs to:

 	miyu% pi -qFL /usr/pkg/bin/tcsh
 	/usr/pkg/bin/tcsh
 	/usr/pkg/man/man1/tcsh.1
 	/usr/pkg/share/nls/C/tcsh.cat
 	/usr/pkg/share/nls/et_EE.ISO_8859-15/tcsh.cat
 	...

The list of files is also used to create binary pkgs, and if it was 
included, it would not only be deleted, but also included into binary 
pkgs, which is not wanted.

I think that's more complex than needed, as you'd have to note what files 
the @exec calls create. You can just @unexec the necessary actions to 
remove them.

Feel free to send me a patch for pkg_info.1 that tells that files created 
by @exec are not included. :)
