 Building ports in parallel is considered unsafe and is generally a bad idea.  The goal of this project is make building multiple ports at one time as safe as possible, and eventually enable parallel dependency building.

+===== Project Update 07/07/2008 =====
+  * bsd.parallel.mk has been added to hold information and the safe fake-pkg target, for the time being.
+  * Entry lock has been added in the form of BASE_LOCK, which is by default set to ${.CURDIR}/.working.  Any action on a port by a user (with ALLOW_PARALLEL defined) immediately acquires this lock and recurses.
+  * The *-depends targets have been changed so that all dependencies are given their own targets ('depname'-subtarget).
+  * For all subtargets, a lock on BASE_LOCK in the dependency directory has been added, to that working dependencies aren't simply written off as not found.
+  * For package registration, a new fake-pkg has been created (in bsd.parallel.mk) that first builds registration information in DUMPDIR (${WRKDIR}/pre_reg) by default, then acquires a lock on PKG_DBDIR, and registers the port.  Not yet implemented is a check for working ports what may conflict with a registering port.
+  * Locks added for distfile and patchfile fetching in do-fetch.  A lock file named after the file to be fetched is created in DISTDIR, and removed once fetch has run.
+  * A FAKE_J flag has been added, and it will be used instead of passing a -j argument  It is not working yet.
+===== Project Update 08/14/08 =====
+  * All modified target moved into bsd.parallel.mk.
+  * pkg_add and pkg_delete modified to honor locks on PKG_DBDIR.
+  * FAKE_J implemented, though testing is needed.
+  * Parallel fetching has been implemented with a modified do-fetch target.
