# Build and upload the xcat-core code.
# Getting Started:
#  - Check out the xcat-core svn repository (either the trunk or a branch) into
#    a dir called <rel>/src/xcat-core, where <rel> is the same as the release dir it will be
#    uploaded to in sourceforge (e.g. devel, or 2.3).
#  - You probably also want to put root's pub key from the build machine onto sourceforge for
#    the upload user listed below, so you don't have to keep entering pw's.  You can do this
#    at https://sourceforge.net/account/ssh
#  - Also make sure createrepo is installed on the build machine
#  - Run this script from the local svn repository you just created.  It will create the other
#    directories that are needed.

# Usage:  buildcore.sh [attr=value attr=value ...]
#		PROMOTE=1 - if the attribute "PROMOTE" is specified, means an official dot release.
#					Otherwise, and snap build is assumed.
# 		UP=0 or UP=1 - override the default upload behavior 
# 		SVNUP=<filename> - control which rpms get built by specifying a coresvnup file

# you can change this if you need to
