[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' for 'pear make-rpm-spec' command, ./builder for fetching sources.
# You should have all PEAR packages installed to get best results (needed for epoch autodetection)
# So far there are 3 packages with epoch > 0:
# $ grep ^Epoch:.* php-pear-*.spec | grep -v 'Epoch:.*0'
# php-pear-MDB2.spec:Epoch:               1
# php-pear-MDB.spec:Epoch:                1
# php-pear-PEAR.spec:Epoch:               1
#
# To create completely new PEAR package spec, follow something like this:
# $ pear download RDF-alpha
# File RDF-0.1.0alpha1.tgz downloaded
# $ pear make-rpm-spec RDF-0.1.0alpha1.tgz
# Wrote RPM spec file php-pear-RDF.spec
# $
#
# 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 of 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
