## This script assembles the sources for the various
## libraries and binaries needed by src2pkg into one
## src2pkg-helpers-x.x.tar.bz2 archive.

## The combined archive contains the sources for
## libsentry, tar-1.13 and coreutils and unionfs-fuse
## Some extraneous material is removed from the original
## archives by this script, to save space in the archive.

# Everything is done locally for this build, as it is really
# only of use to me for preparing the archive which gets
# included in the src2pkg package.
