A small script to copy distfiles from per-port directory to central

location.

This is done to avoid write-on-write race conditions, when two package
builds try to write the same distfile back into the server.  To avoid
this, the distfiles are first copied over to
distfiles/.pbtmp/${PKGNAME}, and then a .done file is created in that

directory.  This script runs on the server periodically to copy the
files to the central location.  Since this script copies one distfile
at a time, the race mentioned above doesn't exist.  Also, it will only
copy files from directories where the .done file exists to avoid
read-before-write race conditions.
