rpm query is slow, cache it

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

#!/bin/sh
# will build package, skipping %prep and %build stage
# i use it a lot!
#
# -glen 2005-03-03
#
# Usage:
# do %install and rpm package, skips %clean
# SPECS$ ./repackage.sh kdelibs.spec
#
# after that is done you could try only package creation (as %clean was
# skipped), for adjusting %files lists:
# SPECS$ ./repackage.sh kdelibs.spec -bb
#
# See also: SPECS/compile.sh
#
# TODO
# - make builder to understand -bi and use builder for short-circuit
