"extract" script for extraction. Many cases where a custom EXTRACT_CMD
simply copied the distfile into the work directory are no longer
needed. The extract script also hides differences between pax and
tar behind a common command-line interface, so we no longer need code
that's conditional on whether EXTRACT_USING is tar or pax.
In the vast majority of cases, nothing has changed (i.e. .tgz, .tar.gz,
and .tar.bz2).
EXTRACT_USING_PAX can be set as before.
For custom extractions, instead of using EXTRACT_BEFORE_ARGS,
EXTRACT_AFTER_ARGS and EXTRACT_CMD, simply set EXTRACT_CMD to be the
command needed to decompress and extract the lements from the archive.
${DOWNLOADED_DISTFILE} can be used to reference the distfile(s).
e.g. for compressed shars, where previously there was:
EXTRACT_CMD= ${GZCAT}
EXTRACT_BEFORE_ARGS=
EXTRACT_AFTER_ARGS= |sh
now use:
EXTRACT_CMD= ${GZCAT} ${DOWNLOADED_DISTFILE} | ${SH}
package uninstalled, with the exceptionof lmbench. Make non-batch
targets for all the benchmarks, and create a results target which
places all the results in /tmp for easier collection.
