# Usage:
# pkgsize [du_size_option] [package] ...

# default du_size_option: -b
# valid du_size_option: -k|-m|-b
# Using options -m,-k will lead to  unexact total values

# Example Usage 1 -> count size of all packages (Kb):
# pkgsize -k|sort -n

# Example Usage 2 -> count size of coreutils and glibc (Bytes):
# pkgsize  coreutils glibc
