# This utility rolls a tarball.
# It takes a single argument:
#	the path to the ebuild the tarball is for.
# A second optional argument is the gentoo username
# It autodetects what the name of the tarball should be,
# creates the tarball, and drops it on 
# /space/distfiles-local on dev.gentoo.org
# (It get's your username from CVS information)
# It also modified the GENTOO_PATCHSTAMP variable in the ebuild
# to have the same datestamp the tarball is named after.
