- existing epoch is enough

[packages/rpm-build-tools.git] / pearize.sh

#!/bin/sh
# updates php-pear .spec with Requires/Conflicts lines.
# the items are added randomly to the preamble, but once added their order is left intact.
# it is still better than nothing. if somebody wishes to add sorting in this
# script. i'd be just glad :)
#
# needs pear makerpm command.
# requires tarball to exist in ../SOURCES.
# you should have all pear packages installed to get best results
#
# todo: adjust similiarily noautoreqdeps
# bugs: the beta portions in version deps could be wrong (php-4.3.0b1 and alike)
# see php-pear-DBA_Relational.spec
# SOmething strange: Requires:	php-common < 4:3:5.1
#
# note: old version pf this script which was used to convert to new package format is in CVS branch MIGRATE
# send blames and beer\b\b\b\bideas to glen@pld-linux.org
