       Description: 
       
       There is one very handy package on OpenBSD named `pkglocatedb`
       which provides the command `pkglocate`.
       
       If you need to find a file or binary/program and you don't know
       which package contains it, use pkglocate.
       
           $ pkglocate */bin/exiftool  
          
       p5-Image-ExifTool-12.00:graphics/p5-Image-ExifTool:/usr/local/bin/exift
       ool
       
       With the result, I know that the package `p5-Image-ExifTool` will
       provide me
       the command `exiftool`.
       
       Another example looking for files containing the pattern "libc++"
       
           $ pkglocate libc++
           base67:/usr/lib/libc++.so.5.0
           base67:/usr/lib/libc++abi.so.3.0
           comp67:/usr/lib/libc++.a
           comp67:/usr/lib/libc++_p.a
           comp67:/usr/lib/libc++abi.a
           comp67:/usr/lib/libc++abi_p.a

       As you can see, base sets are also in the database used by pkglocate,
       so you can easily find if a file is from a set (that you should
       have) or if the file comes from a package.
       
       
       ## Find which package installed a file
       
       Klemmens Nanni (kn@) told me it's possible to find which package
       installed a file present in the filesystem using `pkg_info` command
       which comes from the base system. This can be handy to know from
       which package an installed file comes from, without requiring
       pkglocatedb.
       
           $ pkg_info -E /usr/local/bin/convert
           /usr/local/bin/convert: ImageMagick-6.9.10.86p0
           ImageMagick-6.9.10.86p0 image processing tools
       
       This tells me `convert` binary was installed by ImageMagick package.
