# Paths to skeleton port's source & real Slackware source tree:
export CWD=$SLACKSOURCE/$PKGSERIES/$PKGNAM
export PORTCWD=$PWD

# Temporary build locations:
export TMPBUILD=$TMP/build-$PKGNAM
export PKG=$TMP/package-$PKGNAM
mkpkgdirs # Delete & re-create temporary directories then cd into $TMPBUILD

# Extract source:
mkdir -p ast-base/lib/package/tgz
cp -favv $CWD/*.tgz ast-base/lib/package/tgz

# For Slackware ARM, wipe the old versions in Slackware x86 and replace
# with newer ones which work on newer systems:
# x86 now has a newer version, but let's keep this around in case we need it again
# (I recall it taking quite some time to figure out ksh93..)
#rm -fv ast-base/lib/package/tgz/INIT.*.tgz
#rm -fv ast-base/lib/package/tgz/ast-ksh.*tgz
#rm -fv ast-base/lib/package/tgz/ast-ksh-locale* ## Fedora does not ship this... perhaps in 2012v it's not needed?

# Copy in newer ones:
# again, don't do this anymore.
# We've recompressed the sources from using gzip to using LZMA, to save space:
#cp -favv $PORTCWD/sources/*.t*z* ast-base/lib/package/tgz/
# Repack the sources using gzip, since the ksh build system expects it:
#( cd ast-base/lib/package/tgz/
#  xz -d *xz
#  gzip -1 *.tar )

cd ast-base/
# ARM only - as we gzip the stuff for ksh's build system, and gzip suffixes with .gz not .tgz
