Import plist-utils as pkgtools/plist-utils

Browse source 
The plist-utils suite aims to facilitate management of PLIST entries.
It handles PLIST options and variables, and is especially useful for
keeping PLISTs of packages with quickly changing file-lists, such
as those closely tracking upstream development branch, up to date.

1. Recognize ${KEY} and replace in keys with VALUE
Spawn a command like:
make show-var VARNAME=KEY
And get the KEY value
2. Port to !NetBSD platforms with libnbcompat
3. Use popular precomputed ${KEYS} used in PLISTs like ${PKGBASE}
