# Show the size on disk for a package
## SYNOPSIS:
## .Nm
## .Op Ar pkg...
## DESCRIPTION:
## .Nm
## calculates the sizes of given
## .Ar packages
## using the files from the package manifest and outputs a total size of the
## packages along with all the files associated with them.
## CAVEATS:
## .Nm
## uses the non-POSIX
## .Fl h
## and
## .Fl c
## flags for
## .Xr du 1 ,
## which will not work with
## .Em sbase ,
## but it is a major performance improvement compared to calculating
## total and human-readable sizes by hand.
