Revision 1.1, Sat Oct 1 18:37:15 2016 UTC (7 years, 6 months ago) by kamil
Import plist-utils as pkgtools/plist-utils 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. Import approved by <wiz>. |
